PCT No. PCT/EP95/01451 Sec. 371 Date Dec. 16, 1996 Sec. 102(e) Date Dec. 16, 1996 PCT Filed Apr. 18, 1995 PCT Pub. No. WO96/33464 PCT Pub. Date Oct. 24, 1996One or more processing units are connected with a clock component (comprising a clock) over a bi-directional serial link, and data frames are transmitted between the clock component and the processing units. The clock component may contain a serial link combination circuit for combining multiple processing unit serial links, operating in parallel, into a single serial link connected to the clock. Both of the clock component and the processing units contain an error detection and correction mechanism which examine and modify data within the data frames to perform error detection and correction. The clock component optionally contains an external interface for connection to a command-issuing Service Processor.
