Memory controller for AHB, dual (or multi) channel

David

Hi, I am looking for a memory controller for AHB, dual (or multi) channel.

I found one in the ARM site but for AXI.

Thank you

    Hi MJD,

    What kind of memory are you trying to interface to? If it's SRAM or flash then the Cortex-M System Design Kit includes some examples.

    If you want DRAM (e.g. DDR3/4) then the latest controllers from ARM are using AXI as this gives the highest performance. If you have any AXI components (e.g. processors) in your system then you should consider an AXI memory controller as this would allow multiple outstanding transactions and higher DRAM utilization.

    Thanks,

    Neil.
