8.10.13 Data Modification Module (DMM)

A Data Modification Module (DMM) gives the ability to write external data into the device memory.

The DMM has the following features:

  • Acts as a bus controller, thus enabling direct writes to the 4GB address space without CPU intervention
  • Writes to memory locations specified in the received packet (leverages packets defined by trace mode of the RAM trace port [RTP] module)
  • Writes received data to consecutive addresses, which are specified by the DMM (leverages packets defined by direct data mode of RTP module)
  • Configurable port width (1, 2, 4, 8, 16 pins)
  • Up to 100 Mbit/s pin data rate
