SRAM Controller Cores




The SRAM Controller Cores are a family of SRAM Controller Cores and Subsystems that provide an SRAM interface peripheral for SOCs. SRAM Cores and Memory Controller combination cores that include SDRAM, SRAM, and Flash Cores are available. Within the SRAM Controller Core family, there are cores with generic application side interfaces and cores with AMBA AHB Bus interfaces. The cores with AMBA AHB Bus interfaces connect seamlessly to the AMBA AHB Bus as AMBA AHB Bus slaves. These SRAM Controller Cores are available as synthesizable Verilog models from Aurora VLSI, Inc.

SRAM Controller

  • ZBT flowthru, ZBT pipelined, syncburst, and asynchronous SRAMs
  • Supports several SRAM types- flow through ZBT synchronous, pipelined ZBT synchronous, flow through syncburst synchronous, SCD syncburst synchronous, DCD syncburst synchronous, and asynchronous SRAMs
  • 32 bit or 64 bit SRAM data bus
  • 512 Kbyte to 512 Mbyte SRAM memory system
  • Pipelined accesses for highest performance
  • 0, 1, or 2 cycle read latency, and 0, 1, or 2 cycle write latency
  • 1, 2, or 4 banks of SRAM
  • 17 to 24 address bits
  • SRAM powerdown supported
  • Pipelined accesses for highest possible performance

AMBA Slave Interface

  • AMBA AHB Bus slave
  • 32 bit or 64 bit AMBA AHB Bus- user configurable
  • Supports all required AMBA AHB Bus features
  • Implements AMBA Bus timeout and RETRY response
  • Read data prefetching
  • Write data packing
  • Same cycle device request/response is supported for highest throughput
  • Handles all data packing/unpacking and data alignment for data transfer sizes that do not match the AMBA Bus width and/or SRAM data bus width
  • User configurable for big or little endian AMBA Bus and memory
  • AMBA Bus and SRAM interfaces can be asynchronous to each other
