Operand - Wikipedia, the free encyclopedia In mathematics, an operand is one of the inputs (arguments) of an operator. The number of operands of an operator is called its arity. The operand may be a processor register, a memory address, a literal constant, or a label. en.wikipedia.org /wiki/Operand   (169 words)

Floating point architecture with tagged operands - Patent 5995991 A special operand generator circuit 22 is provided at the output of the arithmetic section 14 for determining whether or not the result of the arithmetic operation performed in the arithmetic section 14 is a special operand value, and which operand value the result equals. Likewise, if the first operand is to be subtracted from the second operand and the second operand is the zero valued special operand, the result must have a magnitude and exponent that equal the magnitude and exponent of the first operand and a sign of opposite polarity as the second operand. For instance, two ordinary operands are added (subtracted) by normalizing the operand with the smaller exponent relative to the operand with the larger exponent, adding (subtracting) the magnitudes of the two operands, e.g., using a carry look-ahead or carry save adder, and then normalizing the result. www.freepatentsonline.com /5995991.html   (4830 words)

Operand History Table Consider the instruction format below: (Image Omitted) The operand address is computed by adding the contents of the base register to the contents of the index register to the value of the displacement field supplied by the instruction. The operand address is computed by adding the contents of the base register to the contents of the index register to the value of the displacement field supplied by the instruction. The operand history table (O.H.T.) holds the instruction address and operand address of each instruction that computes the same operand address each time it is executed. www.priorartdatabase.com /IPCOM/000044351   (389 words)

Apparatus and method for single operand register array for vector and scalar data processing operations - Patent 5261113 In the memory based model, the operands are transferred directly from the main memory unit to the execution unit and the resulting operands are returned directly to the main memory unit. Instead all the operands in the vector register must be stored into the main memory unit from the vector register and the desired single operand fetched into a scalar register. Field 42 identifies the destination location in the operand register file 320, while field 43 and field 44 are the operand register file 320 locations for the source operands, i.e., the operands to be processed by the coprocessor unit 30. www.freepatentsonline.com /5261113.html   (4204 words)

Decimal Arithmetic - Arithmetic operations Otherwise (both operands are finite), quantize returns the number which is equal in value (except for any rounding) and sign to the first (left-hand) operand and which has an exponent set to be equal to the exponent of the second (right-hand) operand. Otherwise, if the operands are given by x and y, then the result is defined to be x – y × n, where n is the integer nearest the exact value of x ÷ y (if two integers are equally near then the even one is chosen). Otherwise (the operand has a negative exponent) the result is the same as using the quantize operation using the given operand as the left-hand-operand, 1E+0 as the right-hand-operand, and the precision of the operand as the precision setting, except that no flags will be set. www2.hursley.ibm.com /decimal/daops.html   (5532 words)

Type Conversions If the operand type is class-wide, a check is made that the tag of the operand identifies a (specific) type that is covered by or descended from the target type. For each discriminant of the target type that corresponds to a discriminant of the operand type, its value is that of the corresponding discriminant of the operand value; if it corresponds to more than one discriminant of the operand type, a check is made that all these discriminants are equal in the operand value. If the operand value is not null, then the result designates the same object (or subprogram) as is designated by the operand value, but viewed as being of the target designated subtype (or profile); any checks associated with evaluating a conversion to the target designated subtype are performed. www.cs.fsu.edu /~baker/ada/arm_95/RM-4-6.html   (1624 words)

Using and Porting GNU CC - Standard Names Operand 0 is the first of the consecutive memory locations, operand 1 is the first register, and operand 2 is a constant: the number of consecutive registers. Operand 1 is divided by operand 2 to produce a quotient stored in operand 0 and a remainder stored in operand 3. is the mode of operand 0 and operand 1; operand 2's mode is specified by the instruction pattern, and the compiler will convert the operand to that mode before generating the instruction. www.myri.com /scs/L3/doc/gcc_163.html   (3289 words)

Software Development : Postscript III:The Operand Stack of PostScript: Arrays, Variables, Loops and Macro Definitions   (Site not responding. Last check: 2007-09-11) As we remember, all the quantities which are stored in the operand stack were integers except a special element which is used to create referrence point(s) in the operand stack. It is respectively, the popping of two topmost elements from the operand stack, to evaluate their arithmetical sum, and then the pushing of the resulting value into the operand stack as the topmost element. The first operand is always the topmost element of the operand stack here and the second operand is the value of the counter variable of the loop, which is inserted to the operand stack at that step. www.linuxfocus.org /English/July1999/article100.html   (3773 words)

Convert operand to structure offset This command permits to convert all immediate operands of instructions in a range selection to a path of offsets through a structure and its possible sub unions. You can easily see instructions related to the operand by moving the mouse over it, and wait for a hint to be displayed. If the an operand value is >= lower limit and <= upper limit then the operand will be converted to offset, otherwise it will be left unmodified. www.datarescue.com /idabase/idadoc/472.htm   (700 words)

Extended Asm - Using the GNU Compiler Collection (GCC) Each operand is described by an operand-constraint string followed by the C expression in parentheses. You should only use read-write operands when the constraints for the operand (or the operand in which only some of the bits are to be changed) allow a register. The input operands are guaranteed not to use any of the clobbered registers, and neither will the output operands' addresses, so you can read and write the clobbered registers as many times as you like. gcc.gnu.org /onlinedocs/gcc-4.1.1/gcc/Extended-Asm.html   (2808 words)

Software Development : PostScript II: The Operand Stack, Manipulations and Mathematical Operators   (Site not responding. Last check: 2007-09-11) It is also possible to enter elements into the operand stack and to see the contents of the stack in one single attempt. The result is the multiplication of the parameters and is maintained as a new element in the operand stack. So, deliberately or by mistake, to give a command which needs parameter(s) onto the operand stack without parameter values, will cause either a complaintabout the parameter(s) which are some topmost elements of the operand stack if they are not suitable for the parameter type, or some top element(s) of the operand stack will be removed. www.linuxfocus.org /English/July1999/article80.html   (2203 words)

What is operand? - A Word Definition From the Webopedia Computer Dictionary In all computer languages, expressions consist of two types of components: operands and operators. Operands are the objects that are manipulated and operators are the symbols that represent specific actions. x and 5 are operands and + is an operator. www.webopedia.com /TERM/O/operand.html   (65 words)

Using and Porting GNU Pascal - Simple Constraints A memory operand is allowed, with any kind of address that the machine supports in general. For example, on the 68000 in a fullword instruction it is possible to use an immediate operand; but if the immediate value is between -128 and 127, better code results from loading the value into a register and using the register. When this operand happens to be a register, the reload pass will be stymied, because it does not know how to copy a register temporarily into memory. cgm.cs.mcgill.ca /labdocs/gpc/gpc_122.html   (1446 words)

Operand Expressions   (Site not responding. Last check: 2007-09-11) Operand expressions are built from operands and operators. Operands are constants, registers, labels, and memory locations. An operand is absolute if its value or offset is entirely known during compilation. www.tmt.com /helphtml/assembler_operand_expressions.htm   (166 words)

Using and Porting GNU CC - Extended Asm The total number of operands is limited to ten or to the maximum number of operands in any instruction pattern in the machine description, whichever is greater. The output operands must be write-only; GNU CC will assume that the values in these operands before the instruction are dead and need not be generated. When the assembler instruction has a read-write operand, or an operand in which only some of the bits are to be changed, you must logically split its function into two separate operands, one input operand and one write-only output operand. www.psc.edu /general/software/packages/gcc/manual/gcc_85.html   (1367 words)

Using the GNU Compiler Collection (GCC) This enables each alternative for different operands to be visually aligned in the machine description even if they have different number of constraints and modifiers. This means that adding a small integer (actually, the width in bytes of the operand, as determined by its machine mode) may be added to the address and the result is also a valid memory address. For example, an address which is constant is offsettable; so is an address that is the sum of a register and a constant (as long as a slightly larger constant is also within the range of address-offsets supported by the machine); but an autoincrement or autodecrement address is not offsettable. www.delorie.com /gnu/docs/gcc/gcc_68   (836 words)

User-defined operand You may specify any string instead of an operand when IDA does not represent the operand in the desired form. IDA proposes the previous manual operand as the default value in the input form. If the "Check operand" checkbox is on, IDA will try to check operand and if the value of the manual operand differs from its original value, will warn you. www.datarescue.com /idabase/idadoc/477.htm   (176 words)

Misty Programming Language: Operators If the operand is a number, then the result is the largest integer which is less than or equal to the operand. If the operand is an object, the result is the number of members in the object. If the left operand is less than the middle operand, then the result is the middle operand and the right operand is not evaluated. www.crockford.com /misty/operators.html   (1720 words)

CS 434 Lecture Notes -- Operand Descriptors In addition to providing a mechanism for communication between high-level code generation routines, the operand descriptor type is an essential component of the interface between the high and low level code-generation modules. Since access to values in registers is generally faster than access to memory, we would like the code we generate to keep intermediate results in registers whenever possible. To make this possible, the routine that "generates code" for the sub-expression "y" has to be able to simply return a descriptor for y where it resides in memory without producing any code. www.cs.williams.edu /~tom/courses/434/outlines/lect7_6.html   (146 words)

Using the GNU Compiler Collection (GCC) When the constraints for the read-write operand (or the operand in which only some of the bits are to be changed) allows a register, you may, as an alternative, logically split its function into two separate operands, one input operand and one write-only output operand. constraint modifier, GCC may allocate it in the same register as an unrelated input operand, on the assumption the inputs are consumed before the outputs are produced. All output operands fall in this category--there is no other way to know which regs the outputs appear in unless the user indicates this in the constraints. gcc.gnu.org /onlinedocs/gcc-3.2.2/gcc/Extended-Asm.html   (2345 words)
