Abstract
A system and method for supporting variable-width memory accesses includes storage registers configured to store transfer data. The storage registers have a pre-determined storage register width. A host interface moves the transfer data to and from the storage registers. The host interface has a data transfer width that is greater than the storage register width. A memory access module analyzes a mode flag that is incorporated into a transfer address. The memory access module performs the memory access operation in a full mode if the mode flag is set to a full access state. Conversely, the memory access module performs the memory access operation in a partial access mode if the mode flag is set to a partial access state. In the partial transfer mode, the transfer data has a data width that is equal to the storage register width. The memory storage module is able to directly access a single one of the storage registers.
