A METHOD FOR ACCESSING A BUS IN A CLUSTERED INSTRUCTION LEVEL PARALLELISM PROCESSOR

摘要

It is switched the basic idea of the invention is that being added along bus, passes through switch described in opened/closed so that the bus is divided into lesser independent segment. Cluster instruction level parallelism processor includes multiple clusters (C1 C6)-(RF), wherein each cluster includes at least one register file and at least one functional unit (FU), bus means (100), for by the cluster (C1-C6), wherein the bus (100) includes multiple bus sectionalizations (100a, 100b, 100c), (200) and has switched means, is disposed in adjacent bus section (100a, 100b, 100c). The switching device (200) is for connecting or disconnecting adjacent total segment (100a, 100b, 100c). In addition, being shown for accessing bus (100) in clustering processor instruction-level parallelism. The bus (100) includes at least one switching device (100) along the bus (200). Cluster can execute sending operation based on source register and migrate word or receive based on source register and transfer word. The switching device is then openedly and closedly according to the transfer word.
