The AXI EMC (Advanced Microcontroller Bus Architecture (AMBA®) Advanced extensible Interface (AXI) External memory controller) provides the control interface for external synchronous, asynchronous SRAM, Flash and PSRAM/Cellular RAM memory devices through the AXI interface. This soft IP core is designed to interface with the AXI 4 Interface.
Key Features
- Supports AXI 4 specification for AXI interface
- Full AXI Slave interface supports 32- Bit Address bus and 32/64-bit data bus
- Supports 32-Bit configurable AXI4 Lite control interface to access internal registers
- Supports Burst transfers of 1-256 beats for INCR burst type and 2, 4, 8, 16 beats for WRAP burst type
- Supports AXI narrow transfers, unaligned transfer type of transactions
- Supports multiple (up to 4) external memory banks
- Supports independent memory configuration of each memory bank
- Supports memory data widths of 64-bit, 32-bit, 16-bit and 8-bit for each of the memory banks
