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 master, 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 65 Mbit/s pin data rate
