OMAPL138BZCE3
TEXAS INSTRUMENTS OMAPL138BZCE3 芯片, 数字信号处理器, 32位, 375/456MHZ, NFBGA-361
The OMAP-L1X series DSP+ARM® low-power Applications Processor based on an ARM926EJ-S and a C674x DSP core. This processor provides significantly lower power than other members of the TMS320C6000™ platform of DSPs. The device enables original-equipment manufacturers OEMs and original-design manufacturers ODMs to quickly bring to market devices with robust operating systems, rich user interfaces and high processor performance through the maximum flexibility of a fully integrated, mixed processor solution. The dual-core architecture of the 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- or 16-bit instructions and processes 32-, 16- or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously.
