Product Description

The LogiCORE™ IP AXI External Memory Controller (EMC) is a soft IP core for use with external memory devices. The adaptable block provides memory controller functionality for SRAM, NOR Flash and PSRAM/CellularRAM memory devices. The core provides an AXI4 Slave Interface that can be connected to AXI4 Master or Interconnect devices in the AXI4 Systems

Key Features and Benefits

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
