Abstract(in English) | We are developing a multi-media RISC processor, V830R/AV, which processes efficiently video data, such that digital TV. The processor integrates a SIMD function unit on V800 series microcontroller architecture, and adapts 2-issue superscaler of a 32-bit function unit and the SIMD function unit. The SIMD function unit operates mostly four 16bit-functions as same as eight 8bit-functions, and two 32bit-functions, and performs efficiently parallel operation, especially video signal processing. The processor encouraged by the SIMD function unit, promises MPEG2 video signal decoding performance. A RDRAM interface circuit embedded in the chip achieves 533Mbyte/s data transmission between the processor and main memories, in order to supply large amount of video data. The processor includes a video interface circuit and an audio interface circuit, and realizes a multimedia system with a little peripheral LSI chips. The die is fabricated with 0.25μm CMOS process, and has about 3.9 million transistors. It works with 200MHz clock on 2.5V power supply, and consumes about 2W. |
