The 620 bus supports the 64-bit PowerPC Architecture specification with a 40-bit physical address bus and a separate 128-bit data bus. The address snoop response is pipelined with the address bus, providing an address transfer rate of up to 33M Addresses/sec at 66 MHz. Completion of address bus operations can be reordered with respect to operation initiation. The address and data buses are explicitly tagged allowing data transfers to be reordered with respect to the addresses. The data bus can transfer up to 1.0 GB/sec at 66 MHz. The bus protocol presented supports the snoop-based MESI cache coherency protocol and direct cache-to-cache data transfers.","PeriodicalId":415918,"journal":{"name":"Digest of Papers. COMPCON'95.

Significant performance gains are possible in the areas of video compression and decompression, as well as other areas of image processing. In this paper, we present a computational complexity analysis of MPEG video decompression, and derive a quantitative performance bound for software MPEG decoders. Based on this estimate, we show that by combining VIS and a high superscalar instruction rate, UltraSPARC is capable of decoding MPEG digital video at 720/spl times/480/spl times/30 resolution entirely in software. A coding example for the YUV to RGB colorspace conversion is also presented.","PeriodicalId":415918,"journal":{"name":"Digest of Papers. COMPCON'95.

This method, called Color Recovery, is a two part process. The first part of the process is to sample true color data generated by an application in order to reduce 24-bit color to 8 bits for storage in the frame buffer. The second part of the process is to use specialized digital signal processing logic to reconstruct the true color image from the 8-bit frame buffer. This part of the process is preformed as the data is being scanned from the frame buffer to the display.","PeriodicalId":415918,"journal":{"name":"Digest of Papers. COMPCON'95.
