  OPCODE
OPCODE is a new small collision detection library.
Hybrid trees (OPCODE 1.3) keep a maximum of 16 triangles per leaf and reorganize client triangle lists, to eventually need roughly 16 times less ram than OPCODE’s standard trees.
Speed hit is often negligible, and volume queries can actually run faster than OPCODE 1.2 due to less cache misses (reorganizing clients arrays also helps in this regard).

  opcode
These opcode blocks are very similar to instruments (and are, in fact, implemented as special instruments), but cannot be called as a normal instrument e.g.
A user-defined opcode block must precede the instrument (or other opcode) from which it is used.
Similarly to instruments, the variables and labels of a user-defined opcode block are local and cannot be accessed from the caller instrument (and the opcode cannot access variables of the caller, either).

  Two Opcode SONICport USB
Opcode is bringing the revolution of USB and ultimate compatability to the world of music production with a line of seven different audio and MIDI USB hardware solutions.
Opcode is already shipping the DATport audio interface which has stereo input and output in the form of two coaxial S/PDIF connectors and retails in the US for $249.95.

  FCD table operations
This core opcode has side effects, as follows: the base frequency of the wavetable t shall be set to x, where x is a value in Hz.
This core opcode has side effects, as follows: index shall be rounded to the nearest integer, and the value of sample number index in the wavetable t shall be set to the new value val, where sample number 0 is the first sample in the wavetable.
The looping continues as long as the opcode is active, and is performed at a special rate which depends on the base frequency basefreq and the sampling rate of the table.

 Opcode - Disable named opcodes when compiling perl code - search.cpan.org
It is strongly recommended that applications using Opcode should use a leading capital letter on their tag names since lowercase names are reserved for use by the Opcode module.
Also, since the number of opcodes in your current version of perl might not be an exact multiple of eight, there may be unused bits in the last byte of an upset.
This tag is simply a bucket for opcodes that are unlikely to be used via a tag name but need to be tagged for completeness and documentation.

  Brainboost - opcode
An opcode is a command that (usually) does something to the circuit board by turning off and on pins in sequence; we can watch the pins to observe the results of a mystery opcode.
An opcode is a hexidecimal number that represents drawing commands and the parameters that affect those drawing commands in a picture.).

 Microcomputer using a double opcode instruction - Patent 4346437
During a single opcode instruction operation, a 4-bit opcode word is fetched from memory (20), is loaded into the instruction register (32), and is applied to a logic circuit (601, 603 or 621, 623).
The opcode applied to the controller causes the microcomputer to step through a sequence of states during which appropriate machine functions occur to accomplish whatever specific task, or operation, is desired by a programmer invoking the instruction.
Such storage of a first opcode in the latches ELAT and MDLAT, followed by a second opcode replacing the first opcode in the instruction register for continuing partial control of the sequence of operations, is referred to as a double opcode operation.

 The MP4-SA Book: Part IV/4: User-Defined Opcodes
If an opcode call uses a signal variable as a calling argument, this variable is passed by reference to the opcode, and the opcode may vary its value.
The return value of an opcode is the scalar or array expression value made by concatenating the values of all the exprs in the return statement, in order of appearance.
It is expanded from the core opcode version of polymorphic rate rules, which we restricted to simplify the introductory explanation of opcode semantics.

 Java bytecode:
You might notice on closer inspection of the bytecode that certain opcodes are prefixed with an `a' or an `i'.
Other opcodes use `b' for byte, `c' for char, `d' for double, etc. This prefix gives you immediate knowledge about what type of data is being manipulated.
The next three opcode instructions at locations 9, 10, and 11 perform the same operation with the second formal parameter to the constructor, num, and the instance variable, idNumber.

 Opcode Information
The operands upon which opcodes operate may, depending on CPU architecture, consist of registers, values in memory, values stored on the stack, I/O ports, the bus, etc. The operations an opcode may specify can include arithmetic, data copying, logical operations, and program control.
Opcodes can also be found in byte codes interpreted by a byte code interpreter (or virtual machine, in one sense of that term).
Here, mnemonic instructions are used that correspond to the opcode and operand specifications of the machine language instructions generated.

 Harmony Central®:
Opcode is reorganizing to strategically position itself for future operations.
As a result, Opcode has now been provided the resources to pursue development opportunities to the point that it can focus its operations toward specific goals, and is in the process of reorganizing to pursue those efforts.
Opcode apologizes for any concern that has resulted from these efforts, and has every confidence that these changes, when completed, promise a more rewarding future for the company and its customers.

 68HC11 Opcode Map
This special opcode is called a "prebyte" since it is a special number which is seen before the actual page-N opcode.
It is interesting to observe that for the 68HC11 opcode mapping, instead of implementing a single prebyte that specifies to find the opcode on a second page, it implements 3 different prebytes which take us to 3 different auxiliary pages.
Only 256 opcodes would be available if the range of values were restricted to the number able to be expressed in a single 8-bit binary number.

 Opcode Cache for Dummies | DevBee
Opcode cache mechanisms preserve this generated code in cache so that it need only be generated a single time to server hundreds or millions of subsequent requests.
Enabling opcode cache will reduce the time it takes to generate a page by up to 90%.
After enabling opcode cache on my own server, I saw page loads drop from about 1.5 seconds to as low as 300ms.
