DSP56321
24-Bit Digital Signal Processor
The Freescale DSP56321, a member of the DSP56300 DSP family, supports networking, security encryption, and
home entertainment using 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 DSP56321 offers 275 million multiply- accumulates per second (MMACS) performance, attaining 550
MMACS when the EFCOP is in use. It operates with an internal 275 MHz clock with a 1.6 volt core and
independent 3.3 volt input/output (I/O) power. By operating in parallel with the core, the EFCOP provides overall
enhanced performance and signal quality with no impact on channel throughput or total channel support. This
device is pin-compatible with the Freescale DSP56303, DSP56L307, DSP56309, and DSP56311.

The DSP56321 is intended
for applications requiring a
large amount of internal
memory, such as networking
and wireless infrastructure
applications. The onboard
EFCOP can accelerate
general filtering applications,
such as echo-cancellation
applications, correlation, and
general-purpose convolution-
based algorithms.
