Audio DSP
Tensilica
1. The HiFi 2 Audio DSP - a click-box option for the Xtensa LX3 processor, so you can do additional optimizations,
2. The 330HiFi pre-configured core that incorporates the HiFi 2 Audio DSP. Just drop it into your SOC design.
3. The HiFi EP Audio DSP - a superset of the HiFi 2 Audio Engine with advanced optimizations for DTS Master Audio, improved voice pre- & post-processing, and improved cache memory subsystem
Over 80 popular audio codecs and sound enhancement software products have been pre-ported to the HiFi Audio architecture, which makes it a "drop-in" block for any SOC application requiring high quality, 24-bit audio capability.
Specialized audio instructions designed into the HiFi Audio DSPs by Tensilica increase code density (reducing memory requirements) and reduce Mhz requirements (lowering power). Techniques used to define these custom instructions include Single Instruction, Multiple Data (SIMD - parallelization), VLIW (multiple operations per cycle), and flexible data path widths (optimum data widths to reduce power).
All of these advanced processor techniques are pre-built into the HiFi hardware, and the codecs supplied by Tensilica utilize this hardware to produce the most efficient programmable audio engine available for licensing.
