The external memory interfaces (EMIFs) of the TMS320C6000 devices
support a glueless interface to a variety of external devices, including:
Synchronous-burst SRAM (SBSRAM)
Synchronous DRAM (SDRAM)
Asynchronous devices, including SRAM, ROM, and FIFOs
An external shared-memory device
The TMS320C6201/C6202/C6701 EMIF services requests of the external bus
from four requesters:
The on-chip program memory controller that services CPU program
fetches
The on-chip data memory controller that services CPU data fetches
The on-chip DMA controller
An external shared-memory device controller
If multiple requests arrive simultaneously, the EMIF prioritizes them and performs
