Latest Patents

R Craig Simpson holds a patent for a "System for operand bypassing to allow a one and one-half cycle cache." This invention features a pipeline structure designed to enable 1.5 cycle access time for both data and instruction cache. It achieves this without imposing additional instruction step delays compared to caches with a 1 cycle access time. The system produces half cycle pulses, allowing various instructions to execute in 0.5 cycles. A bypass signal is generated to make data from a current load instruction available for a second subsequent instruction, despite the 1.5 cycle access time for the data cache. Additionally, a branch address is accessible for a third subsequent instruction, even with the same access time constraints. This invention demonstrates the initiation of an instruction step for each cycle while maintaining efficient cache memory access.
