architecture
The ’C5x’s advanced Harvard-type architecture maximizes the processing power by maintaining two separate
memory bus structures, program and data, for full-speed execution. Instructions support data transfers between
the two spaces. This architecture permits coefficients stored in program memory to be read into the RAM,
eliminating the need for a separate coefficient ROM. The ’C5x architecture also makes available immediate
instructions and subroutines based on computed values. Increased throughput on the ’C5x for many DSP
applications is accomplished using single-cycle multiply/accumulate instructions with a data-move option, up
to eight auxiliary registers with a dedicated arithmetic unit, a parallel logic unit, and faster I/O necessary for
data-intensive signal processing. The architectural design emphasizes overall speed, communication, and
flexibility in processor configuration. Control signals and instructions provide floating-point support,
block-memory transfers, communication to slower off-chip devices, and multiprocessing implementations
as shown in the functional block diagram.
Table 3 explains the symbols that are used in the functional block diagram.
