Digital TVs

When you're designing electronics for digital televisions, you can't design one chip for each model. Usually, one chip design is shared among huge families of models, and features are turned on and off by the host controller depending on the model features and price point. The more programmable the functional blocks, the more flexibility you have to design the chip into several models.

Audio Processing

Most other DSPs and RISC CPUs require two or more cores in order to handle the challenging decoding, re-encoding, and post-processing of audio for Blu-ray playback, but Tensilica can deliver a single HiFi core to handle this challenging workload at a power level lower than any other competing solution. See our Audio, Voice and Speech section.

Digital TV Tuner

Tensilica's DPUs are used in digital TV tuners to handle the computationally demanding tasks, including the Viterbi and Reed-Solomon decoding, the interleaving, and the de-randomization. Wherever there are data streams that need to be quickly processed, Tensilica's DPUs are perfect because the datapath can be matched exactly to the incoming stream for the most efficient real-time processing. See our Signal Processing section.

Video/Graphics Processing

Tensilica's DPUs can be used for video stream processing and video post processing for blocks such as scalars, de-interlacers and image filters. And Tensilica's DPUs can provide the 2D and 3D graphics support required to drive the TV menu system and play games. See our Xtensa product section

Security

It's essential to implement complex security algorithms in a processor in case these algorithms need to be changed. These algorithms are often used throughout the digital TV so people can't pirate copyrighted media and consumer can't access channels for which they haven't paid. See our Xtensa product section.

WiFi

Tensilica's DPUs can be used in both the PHY and MAC layer processing for efficient turbocoding, OFDM filters, FFT, and Viterbi engines. See our Signal Processing section.

Multi-Format DTV Demodulation

The high compute demands of multi-format DTV demodulation are perfect for Tensilica's DPUs, which can be used for DSP as well as function like decision feedback equalizer (DFE) and forward error correction (FEC). See our Signal Processing section.

Applications Processing

Each subsystem often requires an embedded controller. Why not stay with Tensilica, and use our Xtensa processors to do the subsystem control? You can see example configurations of our Xtensa DPUs for control in our Diamond Standard section.
