因此还需要更新renaming table中的available bit. 同理,若consumer指令已经过rename但还没进入issue queue (due to pipeline), 此阶段的指令也需要与wakeup signal相比较,以防出现死锁。若不考虑这一点,issue queue中的src reg可能一直处于not available状态。 若希望减少CAM的数量,可提前将srcID写入issue queue entry...
Computer processor having a pipelined architecture and method of using sameA computer processor that performs operations in a logarithmic number system (LNS) domain includes a log converter (20) which generates log signals, a data pipeline (22), a plurality of processing elements (231a-f) ...
A nem multiple-processor architecture is described that can exploit the instruction level concurrency in numerical processing tasks. The expression processor contains multiple processing elements (PE's), which can be configured either as an SIMD [8] array or as an expression tree pipeline. An expres...
The scalar processor pipeline architecture includes a single pipeline and four stages fetch, decode, execute & result write back. In the single pipeline scalar processor, the pipeline in the instruction1 (I1) works as; in the first clock period I1 it will fetch, in the second clock period ...
