GPU chip is different from DSP (Digital Signal Processing, abbreviation DSP, number in several main aspects
Signal processing) framework.Its all calculating uses floating-point arithmetic, and there are no positions or integer arithmetic to instruct this moment.In addition, by
Image procossing design is aimed in GPU, therefore storage system is actually a two-dimensional fragmented storage space, including a section
Number (therefrom reading image) and two-dimensional address (X, Y coordinates in image).In addition, without any indirect write command.Output writes ground
Location determines by raster processor, and cannot be by routine change.This is for the algorithm among memory for NATURAL DISTRIBUTION
Greatly challenge.Last point does not allow to communicate between the treatment process of different fragments.In fact, fragment processor is one
SIMD data parallel execution unit, independently executes code in all fragments.
In spite of above-mentioned constraint, but GPU still can efficiently perform a variety of operations, from linear algebra and signal processing
To numerical simulation.Although concept is simple, new user still can be puzzled when being calculated using GPU, because GPU needs are proprietary
Graphic knowledge.In this case, some software tools can provide help.Two kinds of high level shading languages CG and HLSL can allow
User writes the code of similar C, is later compiled into fragment process assembly languages.Brook is to aim at GPU to calculate design, and be not required to
Want the high-level language of graphic knowledge.Therefore for the staff that first time is developed using GPU, it can at last one
Good starting point.Brook is the extension of C language, incorporates the simple data multiple programming construction that can map directly to GPU.
The data for storing and operating through GPU are visually likened into " stream " (stream), similar to the array in standard C.Core
It (Kernel) is the function operated on stream.A core function is called to mean on a series of inlet flows real on stream element
Implicit circulation has been applied, i.e., core body has been called to each stream element.Brook additionally provides reduction mechanism, such as flows to one
In all element carry out and maximum value or product calculate.Brook also conceals all details of figure API, and handle completely
The similar two dimensional memory system unfamiliar parts of user many in this way have carried out virtualization process in GPU.It is write with Brook
Application program includes linear algebra subprogram, fast Fourier transform, ray tracing and image procossing.Utilize the X800XT of ATI
With the GeForce 6800Ultra type GPU of Nvidia, condition is executed in identical cache, SSE assembly code optimizing Pentium 4
Under, the speed of many such applications lifts up to as many as 7 times.
