On-chip Nonvolatile AHB Memory Controller
Overview
CoreAhbNvm provides an AHB bus interface and CFI software interface to the embedded nonvolatile memory blocks within Microsemi's Fusion devices, enabling software running on an AHB-based microprocessor to read, write, and erase embedded Flash memory. CoreAhbNvm implements a standard Slave AHB Bus 32-bit hardware interface. This IP core is designed to provide a functional subset of the Common Flash Interface (software interface only) with emphasis given to minimize design size.
