Title: Innovations of Yan Yan Tang

Introduction

Yan Yan Tang is a prominent inventor based in Mountain View, CA (US). He has made significant contributions to the field of technology, particularly in computer graphics and memory management. With a total of 14 patents to his name, Tang's work has had a substantial impact on the industry.

Latest Patents

One of his latest patents is titled "Active block write-back from SRAM cache to DRAM." This invention describes an external cache management unit designed for use with 3D-RAM, which is suitable for computer graphics systems. The unit effectively maintains and tracks the status of level one cache memory in the 3D-RAM. It identifies dirty blocks of cache memory and prioritizes block cleansing based on a least-used algorithm. The invention also provides for periodic block cleansing during empty memory cycles, which can be prompted on demand.

Another notable patent is "Parallel box filtering through reuse of existing circular filter." This patent discloses a sample filtering system and method for concurrently filtering sample data for two or more sequential pixels in a scan-line. The system includes a sample cache, a control register, a read cache controller, and a sample-to-pixel calculation unit. The read cache controller reads a first set of S samples from the sample cache and outputs a second set of S samples to the sample-to-pixel calculation unit. Each subset of samples is selected to cover the filter region for one of the sequential pixels, allowing for separate and concurrent processing.
