The Alma Technologies SPI-MEM-CTRL core is an advanced SPI serial NOR and serial NAND flash memory controller, supporting Single, Dual and Quad I/O SPI accesses and including Boot and Execute on-the-fly features.
The SPI-MEM-CTRL core is designed to provide to a host a simple interface for controlling SPI Serial Flash Memories. The core is highly flexible and can be configured before synthesis or programmed during runtime to support a large number of SPI Serial Flash memories, even less standard ones.
A host can interface to the Serial Flash in a number of ways. Transferring data from the Flash memory to the host is done with minimum effort with a Block Read Interface, which uses a DMA mechanism to transfer a block of data to the host’s memory space. Alternatively, the host can introduce a read request using the core’s programmable registers. Then the core serves this request and sends the necessary instructions to the Serial Flash device. An additional RAM like interface which permits on-the-fly code execution is also available.
The SPI-MEM-CTRL controller has been rigorously verified. A complete verification environment that helps designers verify the functionality and compliance of the core, including additional aids for system-level simulation, are available.
