Low-power DSPs

10 November 2010 DSP, Micros & Memory

Texas Instruments has announced the availability of TMS320C5504 and TMS320C5505 ultra-low-power digital signal processors (DSPs) at 150 MHz, providing 25% higher performance than previous C55x devices. The new processors offer low total power of less than 0,15 mW/MHz and standby power of less than 0,15 mW. Dynamic voltage and frequency scaling can be used to maximise the battery life for different operating conditions, allowing up to 40% additional battery life compared to earlier C55x processors. The C5504 provides up to 256 KB on-chip memory, while the C5505 adds an additional 64 KB on-chip memory, an integrated display controller and fast Fourier transform (FFT) hardware acceleration for end equipments such as noise-cancellation headphones, musical instruments, medical monitoring, biometrics and seismic sensors.
