Latest Patents

One of his latest patents is centered around a communication signal processor architecture. This architecture is designed for a WCDMA baseband system and includes separate processing blocks such as cell search, RAKE receiver, transmitter engine, and error correction. Each block is equipped with a hard-wired logic block and a communication signal processor (CSP). The architecture of each CSP is specifically optimized for its designated signal processing function, featuring a memory architecture that supports simultaneous read and write access.

Another notable patent is for a processor-implemented RAKE receiver. This RAKE receiver utilizes Sub-Word Parallelism (SWP) to enhance performance in WCDMA mobile stations. It is optimized for channel de-rotation and data combining, employing SIMD (Single Instruction, Multiple Data) instructions to perform complex multiplications and additions in a single cycle. This optimization not only reduces power consumption and costs but also enhances performance and provides extensibility for future architectures.
