Megamodule Diagram

The C64x+ Megamodule consists of several components - the C64x+ CPU and associated C64x+

Megamodule core, level-one and level-two memories (L1P, L1D, L2), data trace formatter (DTF),

embedded trace buffer (ETB), the interrupt controller, power-down controller, external memory controller

and a dedicated power/sleep controller (LPSC). The C64x+ Megamodule also provides support for

memory protection and bandwidth management (for resources local to the C64x+ Megamodule).

Figure 5-1 provides a block diagram of the C64x+ Megamodule.
