	CRAY Y-MP EL VECTOR PROCESSING, QUB
		A VECTOR is a series of values eg a Fortran array or a sub-section of it.
		This is stored in a third vector register ie A. The values in the third vector register are stored in the main memory at the location of array A. Time for the multiply alone 103 clock cycles.
		Vector processing changes the order in which operations are performed on individual array elements.

	Vector processor - Wikipedia, the free encyclopedia
		Vector processors were common in the scientific computing area, where they formed the basis of most supercomputers through the 1980s and into the 1990s, but general increases in performance and processor design saw the near disappearance of the vector processor as a general-purpose CPU.
		Vector processing was first worked on in the early 1960s at Westinghouse in their Solomon project.
		Vector processor elements have since been added to almost all modern CPU designs, although they are typically referred to as SIMD.

	Vector processing system for processing plural vector instruction streams - Patent 4849882
		Each of the vector processing units has a resource management circuit, thereby managing its resources and the plurality of memory port logic units as resources and reporting information of the memory port logic unit determined to be used to other vector processing units.
		When a vector processor, or a multiple vector processor constituted by a plurality of vector processing devices, is designed to improve the capacity of vector processing, it is necessary to increase the number of memory port logic units correspondingly.
		Therefore, a multiple vector processor having an architecture in which local memories are each provided in vector processing devices is designed in such a manner that the local memories are indicated in the language specifications and data transmission is effected between the main storage device and the local memories on the user's responsibility.

		Vector register circuitry is provided which includes a vector register file comprising at least one vector register having a plurality of elements, the vector register file further having at least one data port and at least one address port for accessing selected ones of the elements of the vector register.
		Vector processing systems operate on arrays of data (vectors) which can be pipelined through the memory system to reduce the latency problem on all but the first element of the vector.
		Vector register files are also frequently used to store intermediate results from the vector arithmetic units, eliminating the need to store such results in memory and making more efficient use of the memory bandwidth available.

	Vector processing unit capable of reading vector data from a vector register simultaneously to plural resources - ...
		In such a vector processing unit, the data stored in a vector register can be read out with one vector instruction while data is being written into the vector register with another vector instruction, and in such case, these two vector instructions are referred to as being chained.
		In such a vector processing unit, one of the factors determining the vector processing time is the number of chains attained.
		If the vector instruction can be executed, the instruction execution determining circuit 10 adds a number RSN of a resource (an arithmetic unit or a memory requester) to be activated to the vector instruction fed from the instruction register 8.

	Unix: Vector Processing
		Vector processing means that a single program can run multiple math operations at the same time on a single special-purpose processor that can run multiple math operations at the same time.
		In vector processing, you load lots of data into lots of registers, and then you have one set of instructions that operates on all the data at the same time (again, a matrix multiply is the classic example).
		The reason vector processing allows interaction between the operations is that the operations can be things like "multiply each cell(n) with cell(n2) and store the result in cell(n3)", which means that the next instruction gets to see all the new data.

	Raster to Vector Processing for Road Network Analysis
		These vector files may be incorporated into a GIS where the points, lines, and areas are associated with a database of attributes, or they may be analyzed in vacuo to extract information intrinsic to the vectors themselves.
		Vectors are stored without consideration of either geographic parameters (location of a vector on the surface of the earth or within the bounds of an area of interest) or for geodetic parameters (specific projections, ellipsoids, or datums).
		From that point, vectors are created along the raster path in a continuous chain and displayed on the computer monitor, pausing only for operator input where the preset parameters cannot adequately guide a decision, where paths are uncertain at intersections, or where a feature terminates.

		The origins of vector architecure lay in trying to address the problem of instruction bandwidth.

		The MVP is a sum-of-products operation: y=Ax, where y is a vector* with m elements, A is a matrix with m rows and n columns, and x is a vector with n elements.
		The utilization of the vector and scalar registers in each half of the arithmetic unit enables four multiply-adds to take place in each half before further input data is required from bus means 40 and consequently the operation is not delayed by waiting for additional data.
		The vector storage registers may be addressed either directly from the memory address register 82, or from an incremented address supplied by one of the index registers, or as an address supplied by one of the FIFO locations.

		We shall refer to these vectors as A, B and C. The operations of Dot Product and Scalar Multiplication both use a scalar value that we shall refer to as S. The scalar value will also be an integer value.
		The addresses of the vectors A, B and C must be passed as parameters as must the address of the vector to be changed (note: this means that the address of either A or B will be passed twice).

		Processing a vector was much faster even considering the overhead of reading in the file once.
		On average, assuming that the time to read the file was 1 second and we take this out of the vector traversal times, the average time to process the vector is only 0.12 seconds.

	Scalar and Vector Processing
		In vector processing, a change in the order of operations is performed on individual array elements for any loop that includes two separate vectorized operations.
		With vector processing, however, the first line within the loop processes all elements of the array before the second line is executed.
		This equivalence is a fundamental requirement of vector processing.

		Vector computing on the microprocessor is almost a different beast from traditional vector computing in that vectors are defined width-wise rather than length-wise.
		Unlike the Cray ISA, which loads words in sequence up to the vector length (64x64 or 128x64) from memory with a single instruction, the microprocessors load and computes on one wide word at a time (prefetching functions as a pseudo-vector load)...
		The totality of the Cray ISA and architecture is only poorly emulated by the vector operations on the various "vectorizing" microprocessoers.
