High Quality Content by WIKIPEDIA articles! The XSwitch is an interconnect used by the XCore processor. The interconnect protocol is defined by XMOS, and is based around routing messages comprising 9-bit tokens between cores on a network. The protocol is specifically designed for on-chip and board-level communication, but using LVDS drivers it can also run over longer cables. The interconnect routes sequences of messages. A message consists of a header that specifies the core address, a sequence of tokens, and an END-token. There are 512 tokens, 256 of which are data tokens, and 256 of which are control tokens. Data tokens are used to transport data, the control tokens can be used to send in-band control data, in order to implement protocols over the interconnect. A message is routed through a sequence of switches interconnected by Xlinks.
