C64x+ Megamodule
The C64x+ Megamodule consists of several components
—
the C64x+ CPU, the L1 program and data
memory controllers, the L2 memory controller, the internal DMA (IDMA), the interrupt controller,
power-down controller, and external memory controller. The C64x+ Megamodule also provides support for
memory protection (for L1P, L1D, and L2 memories) and bandwidth management (for resources local to
the C64x+ Megamodule).

Memory Architecture
The TMS320C6472 device contains a 608KB level-2 memory (L2), a 32KB level-1 program memory
(L1P), and a 32KB level-1 data memory (L1D).
(L1P), and a 32KB level-1 data memory (L1D).
The L1P memory configuration for the C6472 device is as follows:
•
Region 0 size is 0K bytes (disabled).
•
Region 1 size is 32K bytes with no wait states.
The L1D memory configuration for the C6472 device is as follows:
•
Region 0 size is 0K bytes (disabled).
•
Region 1 size is 32K bytes with no wait states.
