Processor Core
The TMS320VC5510 DSP has a 16-bit core with extensive instruction
pipelining for high performance. See the CPU architecture description
(reference 9) for details. Internally, the DSP utilizes a Harvard architecture
with separate sets of address and data buses for program code and data
accesses. The program address bus is 24 bits wide while the program data bus
is 32 bits wide. Multiple internal data buses, each 16 bits wide, and address
buses, each 24 bits wide, enable simultaneous data fetches or writes to
multiple memory blocks (see “Internal Memory” on page 68).
Where a program code fetch or data access cannot be satisfied from the
internal memory space, it is routed to external memory through the external
memory interface (EMIF) controller. For external accesses, both program
and data accesses occur over a unified 32 bit data bus and 22 bit address bus,
ie. a von Neumann type architecture.
