Title: Innovations by Wei-Hao Chiao: A Pioneer in Instruction Compression and Snoop Filtering

Introduction

Wei-Hao Chiao, an accomplished inventor based in Hsinchu, Taiwan, holds a total of four patents that reflect his deep expertise in advanced computing technologies. His notable contributions primarily focus on methods for instruction compression and snoop filtering mechanisms within multi-processor systems.

Latest Patents

Wei-Hao Chiao's latest innovations include a patent for a method of compressing variable-length instructions, particularly those that are PC-relative. This method involves analyzing program code to identify instruction groups based on preset conditions. After sorting these groups according to a cost function, the first X groups are placed into an instruction table. The original groups in the program code are then replaced with corresponding execution-on-instruction-table (EIT) instructions. The EIT instructions reference the relevant groups in the instruction table, streamlining the execution process for processors.

Another significant patent focuses on the development of a snoop filter for multi-processor systems. This invention incorporates a storage device managed by a control circuit that differentiates between first-type and second-type entries. The first-type entries record information about the first cache and its associated memory addresses, while the second-type entries track information regarding multiple second caches and their memory addresses. Such filtering is crucial for improving system efficiency and speed.
