Title: The Innovations of Chuck Cheuk-wing Cheng

Introduction

Chuck Cheuk-wing Cheng is a notable inventor based in Saratoga, California. He has made significant contributions to the field of microcontroller technology, holding a total of 7 patents. His work focuses on enhancing the efficiency and performance of microcontroller systems.

Latest Patents

One of Cheng's latest patents is titled "Four stage pipeline processing for a microcontroller." This invention discloses a system and method for efficiently processing instructions in a pipeline architecture while maintaining a fixed instruction execution per clock cycle rate. The pipeline consists of four stages: an instruction fetch stage, an operand fetch stage, an execution stage, and a write back stage. In one embodiment, an entire clock cycle is dedicated to the instruction fetch stage to retrieve instruction data from non-volatile memory. The operand fetch stage preliminarily decodes the instruction data to determine tasks, allowing the execution stage to perform time-intensive calculations efficiently. Additionally, a dual port data memory is employed to enable concurrent read and write operations, achieving a one instruction per clock cycle rate.

Another significant patent is the "System and method for multi-input wake up in a microcontroller using a single clock." This invention detects multiple inputs, such as asynchronous transitions or synchronous inputs from the CPU, enabling either input to generate a wake-up signal using a single clock signal. It also resolves conflicts between multiple inputs while utilizing the single clock signal.
