DSPs Touted as Lowest Power Texas Instruments announced the availability of TMS320C5504 and TMS320C5505 ultra-low-power digital signal processors (DSPs) at 150 MHz, providing 25 percent higher performance than previous C55x devices. The processors are said to offer the industry’s lowest total power at <0.15 mW/MHz and standby power at <0.15 mW. The processors feature up to 320 KB of on-chip memory and multiple integrated peripherals that reduce system cost by more than 20 percent compared to earlier C55x processors. Dynamic voltage and frequency scaling can be used to maximize the battery life for different operating conditions, allowing up to 40 percent additional battery life compared to earlier C55x processors. The C5504 DSP is appropriate for emerging portable applications that require up to 256 kB on-chip memory, such as portable voice recorders and MP3 players. The C5505 DSP builds on the C5504 by adding an additional 64 kB on-chip memory, an integrated display controller and fast Fourier transform (FFT) hardware acceleration.
