Latest Patents

One of his latest patents is titled "PIO interjection between beats of a DMA operation." This invention discloses techniques for detecting and interjecting a programmed input/output (PIO) operation into a direct memory access (DMA) operation. In this embodiment, an integrated circuit includes a DMA controller that contains a control circuit, a DMA unit, and a PIO unit. The control circuit is designed to detect a pending PIO operation during a DMA operation and interject the PIO operation onto a shared path during the same clock cycle or the first clock cycle following the detection. This allows for efficient management of multiple single-clock-cycle beats in DMA operations.

Another significant patent is focused on "Cache management instructions." This invention provides techniques for managing a cache within a processor using machine instructions. These instructions can perform various operations on the cache, such as victimization, allocation, and pre-fetching. Notably, these cache management instructions are defined by operands that specify memory addresses within main memory, allowing programmers to manage the cache without needing to know the specific data locations within it.
