....through the pipeline in order with a stage at the end where exCCPnon conditions are checked before the process stae is modified. Examples include the Amdahl 470 and 5g0 [Amdhgl.Amdhg0] and the Gould SEl. 32 g7 [Aardg2] The high performance CDC 6600 [Thor70] CDC 7600 [Buns69] and Cray Research [Russ7g, Cray79] computers allow insu uctions to complete out of Ihe architectural sequence. Consequently, they. have some exption conditions that result in imprecise interrupts. In these machines. the advantages of precise interrupts have been sacrificed in favor of maximum parallelism and design simplici . I O ....

.... is not needed (statistics are given in Section 4) Having the memory address available at issue time has other advantages; for example, store address queue checking can be done as part of the issue function, in much the same way as the Cray 1 does memory bank conflict checking at issue time [7].

....traces were generated for each of the benchmark programs and then used to drive the simulations. No modifications to the code were performed; the code used is that produced by the Cray Fortran Compiler. The simulator uses a processor model that is a slight variant of the CRAY 1S processor [CRAY82,Russ78]. # # The hardware functional units in the simulator have the same performance characteristics as the CRAY 1 functional units; the time taken for a scalar add is 2 clock cycles, floating point multiply take 7 clock cycles, etc. The register files are also configured as in the CRAY 1. The only ....
