Latest Patents

Among Wei C Hsu's latest patents are two groundbreaking inventions that showcase his expertise in profiling instructions and optimization:

1. **Hardware/software system for profiling instructions and selecting a trace using branch history information for branch predictions**: This inventive mechanism enhances performance by providing fast profiling and effective trace selection. It divides the workload between hardware and software, allowing the hardware to automatically detect frequently executed code, known as hot code. The hardware maintains branch history information and signals the software when it identifies hot code, facilitating accurate branch predictions.

2. **System and method using a hardware embedded run-time optimizer**: This invention features an embedded run-time optimization system (RTOS) within the hardware. It sets a threshold value into a counter linked with specific cache lines in the instruction cache (Icache). As instructions are executed, the counter decrements, and upon reaching zero, a trap indicates that the code is hot. A trace selector then optimizes and stores this trace in memory, leading to improved execution efficiency in subsequent operations.
