4.9 Dual Data Movement Accelerator (dMAX)
4.9.1 dMAX Device-Specific Information
The dMAX is a module designed to perform Data Movement Acceleration. The dMAX controller handles
user-programmed data transfers between the internal data memory controller and the device peripherals
on the C672x DSP. The dMAX allows movement of data to/from any addressable memory space,
including internal memory, peripherals, and external memory. The dMAX controller in the C672x DSP has
a different architecture from the previous EDMA controller in the C621x/C671x devices.
The dMAX controller includes features, such as capability to perform three-dimensional data transfers for
advanced data sorting, capability to manage a section of the memory as a circular buffer/FIFO with delay
tap based reading and writing data. The dMAX controller is capable of concurrently processing two
transfer requests (provided that they are to/from different source/destinations).
Figure 4-6 shows a block diagram of the dMAX controller.
