Bus interconnect system for graphic processing system - has individual buses coupling graphics processing elements in ring, with signal lines for transferring command signals between elements

摘要

The system includes a bus structure, coupling a number of graphics processing elements (202,222,242) in a ring. The bus structure comprises a number of individual buses (250,252,254), with each bus connecting a pair of graphics processing elements. - Each individual bus comprises a number of signal lines (250A-250F) for transferring graphics command signals and information signals between graphics processing elements in the ring.
