Abstract
An embedded controller capable of providing direct memory access (DMA) to memory for a host. The controller may include a processor, a memory medium, and an interface coupled to the memory medium. The interface may be configured to couple to a host and receive a DMA request. The DMA request may include a request to read data from a memory location in the memory medium or a request to write data to a memory location in the memory medium. The DMA request may include a relative memory address. The interface may be configured to translate the relative memory address into a first address of the memory medium. Accordingly, the interface may perform operations according to the DMA request using the first address of the memory medium. The processor may be configured to operate according to data stored in the memory medium.
