THE RAPID PROTOTYPING EXPERIENCES OF IMAGE PROCESSING ALGORITHMS ON FPGA

Recent FPGA chips, with their large capacity mem-ory and reconfigurability potential, have opened new frontiers for rapid prototyping of embedded systems. With the advent of high density FPGAs it is now feasible to implement a high-performance VLIW processor core in an FPGA. We describe re-search results of enabling the DSP TMS320 C6201 model for real-time image processing applications, by exploiting FPGA technology. The goals are, firstly, to keep the flexibility of DSP in order to shorten the development cycle, and secondly, to use powerful available resources on FPGA to a max-imum in order to increase real-time performance. We present a modular DSP C6201 VHDL model which contains only the bare minimum number of instruction sets, or modules, necessary for each target application. This allows an optimal imple-mentation on the FPGA. Some common algorithms of image processing were created and validated on an FPGA VirtexII-2000 multimedia board using the proposed application development cycle. Our results demonstrate that an algorithm can easily be, in an optimal manner, specified and then auto-matically converted to VHDL language and imple-mented on an FPGA device with system level soft-ware. 1
