PCI EXPRESS TLP PROCESSING CIRCUIT AND RELAY DEVICE PROVIDED WITH THIS |
摘要 |
A PCI Express TLP processing circuit (10) comprises: a plurality of reception processing sections (2a1); a transmission processing section (2b); and a multiplexer (2c1) that performs transmission to the transmission processing section, selecting one of the reception processing sections; and at least a reception processing section comprises: a redundancy code generating circuit (12); an LCRC/sequential number detection circuit (13); a buffer memory (14); a packet control circuit section (16) that controls transmission for normal transmission to the transmission destination of the TLP in question or for nullifying transmission; and the transmission processing section comprises: a sequential number generating circuit (19); an LCRC generating circuit (20) and a relay circuit error detection circuit (21), whereby data integrity of the transmitted TLP can be guaranteed.
