    I'm a bit confused about the bus structure and memory model of ARM Cortex M3. First of all, does Cortex M3 actually have 3 physically separate buses coming out of it?

    Hi,

    I trying to build the peripheral around Cortex-M0 IP core thorugh AHB-lite system. Right now I have to integrate Cortex-M0 with the DDR2 SRAM (1Gb) through AHB lite.

    I searched on  internet which shows interfacing only through core generator (MIG…

    I see in the documentation site that ARM offers up some bus functional models to simulate both a 32 and a 64 bit AHB bus master in Verilog RTL.

    Where do I find these models, and what is the cost?

    I am working to verify a customer's AHB peripheral, and…

  • Does Cortex-M3/M4 continue with burst in response to ERROR?

    AMBA spec states that 'Master can choose whether to terminate current burst or continue with burst in response to ERROR'.
    What does Cortex-M3/M4 do in response to ERROR? Does it continue with burst in response to ERROR in some special cases?
