Latest Patents

One of Guohua Chen's latest patents is a microprocessor with a multistep-ahead branch predictor. This invention features a branch predictor that is coupled to an instruction cache and employs an N-stage pipelined architecture. It is designed to perform branch prediction to control the instruction fetching of the instruction cache. The branch predictor can predict branches for (N-1) instruction-address blocks in parallel, which includes a starting instruction-address block and (N-2) subsequent blocks. This advanced design allows the branch predictor to stay ahead of the branch prediction for the starting instruction-address block.

Another notable patent is focused on efficient random number generation for update events in a multi-bank conditional branch predictor. This branch predictor consists of multiple memory banks that hold prediction information used to forecast the direction of branch instructions executed by a processor. The invention includes hardware logic that performs arithmetic and/or logical operations on event counts to generate a random value. This random value is then utilized to make decisions about updating the memory banks based on the accuracy of branch predictions.
