DSP56L307
24-Bit Digital Signal Processor
The Freescale DSP56L307, a member of the DSP56300 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 multiply-accumulates per second (MMACS),
attaining 320 MMACS 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.

The DSP56L307 is intended
for applications requiring a
large amount of internal
memory, such as networking
and wireless infrastructure
applications. The EFCOP
can accelerate general
filtering applications, such as
echo-cancellation
applications, correlation, and
general-purpose convolution-
based algorithms.
