DSP56L307 Block Diagram
The Motorola DSP56L307, a member of the
DSP56300 Digital Signal Processor (DSP) family,
supports network applications with general
filtering operations. The Enhanced Filter
Coprocessor (EFCOP) executes filter algorithms in
parallel with core operations, enhancing signal
quality with no impact on channel throughput or
total channels supported. The result is increased
overall performance. Like the other DSP56300
family members, the DSP56L307 uses a
high-performance, single-clock-cycle-per-
instruction engine (DSP56000 code-compatible), a
barrel shifter, 24-bit addressing, an instruction
cache, and a direct memory access (DMA)
controller (see
Figure 1).
The DSP56L307
performs at 160 million instructions per second
(MIPS), attaining 290 MIPS when the EFCOP is in
use. It operates with an internal 160 MHz clock
with a 1.8 volt core and independent 3.3 volt
input/output (I/O) power.
