  abstract= "A multithreaded architecture exploits instruction level
     parallelism by interleaving instructions from disjoint
     thread contexts. As each thread executes within its own
     instruction stream with private data (the context
     registers), there is no interdependency between instructions
     from different threads. This allows high resource
     utilisation of a super scalar pipelined processor at a very
     low cost, in terms of complexity and silicon area. A new
     synchronisation mechanism for a multithreaded architecture
     is outlined. Two new instructions have been introduced to
     perform one to one and n-way synchronisation. The operation
     allows synchronisations to be requested and actioned
     efficiently on chip in as little as four clock cycles.
     Barriers and CSP style channels can easily be constructed
     with this new synchronisation instruction. A brief
     examination of performance of this multithreaded
     architecture shows that the optimum number of contexts per
     multithreaded processing element is four, based on test
     programs."
