/* Asynchronous SDM NoC (C)2011 Wei Song Advanced Processor Technologies Group Computer Science, the Univ. of Manchester, UK Authors: Wei Song wsong83@gmail.com License: LGPL 3.0 or later Router configuration header file for SDM routers. Possible configuration combinations: * Wormhole (set VCN to 1) ENABLE_EOF [ENABLE_CHANNEL_SLICING] [ENABLE_LOOKAHEAD] * SDM (set VCN > 1 without define ENABLE_CLOS) ENABLE_EOF [ENABLE_CHANNEL_SLICING] [ENABLE_LOOKAHEAD] [ENABLE_MRMA] * SDM-Clos (set VCN > 1 and define ENABLE_CLOS) ENABLE_EOF ENABLE_CLOS [ENABLE_CHANNEL_SLICING] [ENABLE_LOOKAHEAD] [ENABLE_CRRD [ENABLE_MRMA]] The combinations not presented above are illegal, which may produce unexpected failures. History: 20/09/2009 Initial version. <wsong83@gmail.com> 23/05/2011 Clean up for opensource. <wsong83@gmail.com> 26/05/2011 Add ENABLE_MRMA and configuration explanations. <wsong83@gmail.com> */ // if VCN > 1, set ENABLE_CLOS to use the 2-stage Clos switch for less switching area // `define ENABLE_CLOS // Using the asynchronous virsion of the Concurrent round-robine dispatching // algorithm for the 2-stage Clos can save some area but introduce a 5% // throughput loss // `define ENABLE_CRRD // for the SDM router using crossbars and the Clos router using CRRD // algorithm, using the multi-resource match arbiter may save the area in // switch allocators // `define ENABLE_MRMA // set to enable channel slicing for fast data paths // `define ENABLE_CHANNEL_SLICING // set to use the early acknowledge of lokkahead pipelines in the critical cycle // `define ENABLE_LOOKAHEAD // always set in wormhole and SDM routers to enable the eof bit in data pipeline stages `define ENABLE_EOF
