Abstract :
A minimalistic set of multimedia introductions introduced into PA-RISC microprocessors implements SUID-MIMD parallelism with insignificant changes to the underlying microprocessor. Thus, a software video decoder attains MPEG video and audio decompression and playback at real-time rates of 30 frames per second, on an entry-level workstation. Our general-purpose parallel subword instructions can accelerate a variety of multimedia programs
