Continued research into Intel's i960 architecture has resulted in the development of performance improvements beyond those implemented in the i960CA microprocessor. These improvements allow additional superscalar dispatch opportunities, reduce memory access delays, and enhance the performance of specific instructions. The i960MM microprocessor is an implementation of these performance enhancements. Together, these enhancements can increase the performance of certain applications by 25% to 100%. Additionally, the i960MM includes an implementation of a full-function floating-point unit. Performance of 27 MFLOPs (single precision) and 16 MFLOPS (double precision) was achieved on the Linpack benchmarks at 40 MHz.>
