Abstract :
A programmable data-path that supports MPEG standards Synthetic & Natural Hybrid video Coding (SNHC) is presented. It can support a maximum of 16 parallel SIMD integer operations and 2 parallel SIMD floating-point operations. Two new instructions were added in order to increase the execution of 3D graphics and SNHC as well as to speed up IDCT, FFT, and other media signal processing algorithms. These operations are implemented by re-using the hardware without significant increase in area and delay. The datapath has been modeled in Verilog using 0.25u CMOS library and synthesized using Synopsys. All operations are single-cycle running at 200 MHz.
