Description
The OMAP-L137 device is a low-power applications processor based on an ARM926EJ-S and a
TMS320C674x DSP core. It consumes significantly lower power than other members of the
TMS320C6000™ platform of DSPs.
The
OMAP-L137
device
enables
original-equipment
manufacturers
(OEMs)
and
original-design
manufacturers (ODMs) to quickly bring to market devices featuring robust operating systems support, rich
user interfaces, and high processing performance life through the maximum flexibility of a fully integrated
mixed processor solution.
The dual-core architecture of the OMAP-L137 device provides benefits of both DSP and Reduced
Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C674x DSP core
and an ARM926EJ-S core.
The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and
processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and
memory system can operate continuously.
