The video signal processor AxPe1280V has been developed forimplementation of different video coding applications accordingto standards like ITU-T H.261/H.263, and ISO MPEG-1/2.Itconsists of a RISC processor supplemented by a coprocessor forconvolution-like low-level tasks.RISC and coprocessor have beenimplemented in a standard cell design combined with full-custommodules.The processor was fabricated in a 0.5 µm CMOS technologyand has a die size of 82 mm{2}.It provides a peak performanceof more than 1 giga arithmetic operations per second (GOPS) at66 MHz.For processing of very computation-intensive algorithmsor high data rates, several processors can be bus-connected to forma MIMD multiprocessor system.
