Machine organization of the IBM RISC System/6000 processor

by G. F. Grohoski
The IBM RISC System/6000® processor is a second-generation RISC processor which reduces the execution pipeline penalties caused by branch instructions and also provides high floating-point performance. It employs multiple functional units which operate concurrently to maximize the instruction execution rate. By employing these advanced machine-organization techniques, it can execute up to four instructions simultaneously. Approximately 11 MFLOPS are achieved on the LINPACK benchmarks.
