  • Includes internal clock-crossing circuitry between the local bus interconnect and the external memory channel to reduce circuit area and improve the performance of the customer’s design
  • Excellent memory access performance for both latency sensitive and bandwidth intensive applications:
    • The round trip time for read memory transfer requests through the memory controller has been optimized for latency sensitive applications, such as processor cores.
    • The memory controller supports long burst memory transfer requests over the memory channel to sustain high effective memory bandwidth (>90% efficiency of memory channel)
    • Note:  SLL offers a range of cache technologies to significantly increase the performance of  processor cores that do not have internal instruction and/or data caches when accessing external memories.
  • Features low circuit area and low SRAM usages, making SLL’s memory controller viable for use in resource constrained designs. 
  • Includes optional support for automatic configuration of memory devices at power on:
    • FPGA customers typically use the automatic configuration option
    • This dramatically simplifies integration of SLL’s memory controller in customer designs, enabling all firmware to be executed in place from x8 NOR Flash.  
  • Include support for manual configuration of the memory controller and any attached memory devices
    • ASIC customers typically use the manual configuration option
    • ASIC customers can prototype their designs in FPGA with manual configuration option enabled
