Realization of a programmable parallel DSP for high performance image processing applications

Abstract

Architecture and design of the HiPAR-DSP, a SIMD controlled signalprocessor with parallel data paths, VLIW and novel memory design.The processor architecture is derived from an analysis of thetarget algorithms and specified in VHDL on register transfer level.A team of more than 20 graduate students covered the whole designprocess, including the synthesizable VHDL description, synthesis,routing and backannotation as the development of a complete softwaredevelopment environment.The 175mm{2}, 0.5µm 3LM CMOSdesign with 1.2 million transistors operates at 80 MHz and achievesa sustained performance of more than 600 million arithmetic operations.
