FPGA can use together with DSP processor, as independent preprocessor The device, or is regarded as the coprocessor. In the preconditioning framework, FPGA lies and responsible for the signal preconditioning in the data highway directly, treated signal can with transfer to DSP processor to go on the lower subsequent processing of the speed economically while being high-efficient in advance.
In the coprocessing framework, FPGA and DSP stand side by side and put, the latter unloads the particular algorithm function to FPGA, in order to realize and adopt more high processing rate of DSP processor achievable speed than alone. Passes DSP back, or send to other devices and further deal with, transmit or store in result of FPGA (Fig. 1) .
Choose preconditioning, after treatment to be still the coprocessing, often depend on required sequence excess and influence on delaying in whole of the Mobile Data between processor and FPGA... Read more
