Latest Patents

One of Alex's latest patents is focused on a DMA transfer method for a system that includes a single-chip processor with a processing core and a device interface operating in different clock domains. This innovation features a single-chip central processing unit (CPU) that integrates a processing core and a complete cache-coherent I/O system, which operates asynchronously with the processing core. The internal communications protocol utilizes synchronizers and data buffers to facilitate the transfer of information between the clock domains. This design enhances throughput by allowing the processing unit direct access to the I/O system, eliminating delays typically associated with external I/O chip-sets. Additionally, the system holds data from one DMA transfer in the data buffer for subsequent transfers, further increasing efficiency.

Another significant patent by Alex is for a low-latency, high-throughput integrated cache coherent I/O system. Similar to his previous work, this patent describes a single-chip CPU that includes a processing core and a cache-coherent I/O system. The innovative design employs synchronizers and data buffers to manage information transfer between clock domains, ensuring high throughput and low latency. The integrated I/O system also features a dedicated memory management unit that includes a translation lookaside buffer, converting I/O addresses to physical addresses for the processing core.
