Product Summary

The TMS320C31PQL50 is a 32-bit, floating-point processor, manufactured in 0.6 mm triple-level-metal CMOS technology. The TMS320C31PQL50 is a part of the TMS320C3x generation of DSPs from Texas Instruments. The device’s internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 80 million floating-point operations per second (MFLOPS). The TMS320C31PQL50 optimizes speed by implementing functions in hardware that other processors implement through software or microcode. This hardware-intensive approach provides performance previously unavailable on a single chip.
