Disclosed approaches eliminate involving a bus interface in polling by the host computer system and the peripheral component for events to coordinate direct memory access (DMA) transfers. The host polls main memory for DMA events communicated by the peripheral component, and the peripheral component polls local registers for DMA addresses to initiate DMA transfers. DMA transfers are initiated by the host storing main memory addresses in the local registers of the peripheral component, and DMA events generated by the peripheral component are stored in the main memory.

Direct memory access circuitry and method

A database proxy includes a computing device and a hardware-accelerated database proxy module. The computing device and the database proxy module. The database proxy is configured to receive a write request from a client; store the write request in a commit log in a first non-volatile memory device; in response to storing the write request in the commit log, return to the client a signal acknowledging success of the write request; store the write request in a cache in a second non-volatile memory device; cause the write request to be written in a database store; and based on a first determination that the write request is stored in the cache and on a second determination that the write request is written in the database store, remove the write request from the commit log.
