摘要
A VLIW processor has a hierarchy of functional unit clusters that communicate through explicit control in the instruction stream and store data in register files at each level of the hierarchy. Explicit instructions transfer values between sub-clusters through a cluster level switch network. Transfer instructions issue in dedicated instruction issue slots in parallel with instructions that perform computation in functional units. The switch network can perform permutations on the data being moved. The switch network enables for operands to be broadcast between the sub-clusters, global register file and memory.
