Latest Patents

One of Chen's latest patents is titled "Selective zero extension based on operand size." This innovation allows a processor to support multiple operand sizes, such as 8, 16, 32, and 64 bits. The processor intelligently determines how to update a destination register when an operand size smaller than the largest is used. In specific embodiments, it zero extends 32-bit operands while preserving values for 8 or 16-bit operands.

Another significant patent is "Branch predictor index generation using varied bit positions or bit order reversal." This invention involves an indirect branch predictor that utilizes a buffer to store branch target addresses from previously executed indirect branch instructions. The buffer is indexed using history information and the program counter (PC) of the instruction being predicted. Various techniques are employed to enhance prediction accuracy, including offsetting and weighting history information, as well as reversing the bit order of the PC.
