Abstract: 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.

Abstract: 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.

Abstract: A database proxy includes a computing device and a hardware-accelerated database proxy module. The computing device includes one or more processors, memory, a first bus interface, and a network interface coupling the database proxy to one or more networks. The database proxy module includes a second bus interface coupled to the first bus interface via one or more buses, and a request processor. The database proxy is configured to receive a database read request from a client via the one or more networks and the network interface; forward the database read request to the request processor using the one or more buses; process, using the request processor, the database read request; and return results of the database read request to the client. In some embodiments, the computing device or the database proxy module further includes a flash memory interface for accessing one or more flash memory devices.
