Title: Yung-Chun Lei: Innovator in Audio and Booting Technologies
Introduction
Yung-Chun Lei is a prominent inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the fields of audio decoding and booting systems. With a total of 5 patents to his name, his work continues to influence technological advancements.
Latest Patents
One of Yung-Chun Lei's latest patents is a decoding apparatus and decoding method for multiple audio standards. This invention discloses a decoding apparatus designed to decode an analog audio signal. The apparatus includes an RF tuner, an analog to digital (A/D) converter, a digital down converter, and a programmable digital signal processor (DSP). The RF tuner receives the analog audio signal and provides an analog sound intercarrier frequency (SIF) signal indicative thereof. The A/D converter samples the analog SIF signal and converts it into a digital SIF signal. The digital down converter down converts the digital SIF signal to generate a baseband signal. The programmable DSP demodulates the baseband signal according to a predetermined standard and decodes the demodulated baseband signal to output an output signal in compliance with the decoding procedure of the predetermined standard.
Another notable patent is a system for booting from a non-XIP memory utilizing a boot engine that does not have ECC capabilities during booting. This booting system includes a non-XIP memory for storing a boot loader code and multiple operating system (OS) images, which correspond to the same source image. An XIP memory stores a shadowed boot loader code and OS images. A Central Processing Unit (CPU) executes the OS images stored in the XIP memory. The system also features a code shadowing module for performing error detection checking on the OS images in the non-XIP memory and shadowing the boot loader code and OS images to the XIP memory. A non-XIP interface enables the boot engine to access the non-XIP memory.
