Tensilica Inc. was a company based in Silicon Valley that developed semiconductor intellectual property (SIP) cores. Tensilica was founded in 1997 by Chris Rowen.[1] In April 2013, the company was acquired by Cadence Design Systems for approximately $326 million.[2]
Products
[edit] | This section may contain excessive or inappropriate references to self-published sources. (November 2024) |
Cadence Tensilica develops SIP blocks to be included on the chip (IC) designs of products of their licensees, such as system on a chip for embedded systems. Tensilica processors are delivered as synthesizable RTL to aid integration with other chips.
Xtensa configurable cores
[edit]Xtensa processors range from small, low-power cache-less microcontroller to more performance-oriented SIMD processors, multiple-issue VLIW DSP cores, and neural network processors.[3] Cadence standard DSPs are based on the Xtensa architecture.[4] The architecture offers a user-customizable instruction set through automated customization tools that can extend the base instruction set, including and not limited to, addition of new SIMD instructions and register files.[5][6]
Xtensa instruction set
[edit]The Xtensa instruction set is a 32-bit architecture with a compact 16- and 24-bit instruction set. The base instruction set has 82 RISC instructions and includes a 32-bit ALU, 16 general-purpose 32-bit registers, and one special-purpose register.[7]
Audio and voice DSP IP
[edit]
| This section contains promotional content. (November 2024) |
- HiFi Mini Audio DSP — A small low power DSP core for voice triggering and voice recognition[8]
- HiFi 2 Audio DSP — DSP core for low power MP3 audio processing[9]
- HiFi EP Audio DSP — A superset of HiFi 2 with optimizations for DTS Master Audio, voice pre- and post-processing, and cache management[10]
- HiFi 3 Audio DSP — 32-bit DSP for audio enhancement algorithms, wideband voice codecs, and multi-channel audio[11]
- HiFi 3z Audio DSP — For lower-powered audio, wideband voice codecs, and neural-network-based speech recognition.[12]
- HiFi 4 DSP - Higher performance DSP for applications such as multi-channel object-based audio standards.[13]
- HiFi 5 DSP - For digital assistants, infotainment, and voice-controlled products.[14]
Vision DSPs
[edit]- Vision P5 and P6 DSP.[15][16][self-published source?]
- Vision C5 DSP, for neural network computational tasks.[17][self-published source?]
Adoption
[edit]- AMD TrueAudio, available in select GPU products based on the GCN2 microarchitecture, integrates an HiFi EP Audio DSP on-die.[18] Hardware integration of the DSP is dropped since GCN4, with TrueAudio Next switching to a GPGPU-based approach.[19]
- Microsoft HoloLens incorporates a custom coprocessor fabricated on TSMC's 28nm process node, integrating 24 Tensilica DSP cores. It has around 65 million logic gates, 8 MB of SRAM, and 1 GB of low-power DDR3 RAM.[20]
- Espressif ESP8266 and ESP32 Wi-Fi IoT SoCs use respectively the "Diamond Standard 106Micro" (by Espressif referred to as "L106")[21] and the LX6.[22]
- Spreadtrum, licensing the HiFi DSP.[23][self-published source?]
- VIA Technologies, using the HiFi DSP in an embedded SoC.[24][self-published source?]
- Realtek standardized on the HiFi audio DSP for mobile and PC products.[25][self-published source?]
History
[edit]- In 1997, Tensilica was founded by Chris Rowen.
- Five years later, Tensilica released support for flexible length instruction encodings, known as FLIX.
- By 2013, Cadence Design Systems acquired 100% of Tensilica.
Company name
[edit]The brand name Tensilica is a combination of the word Tensile and Silica, with the latter referring to silicon, the building blocks of modern integrated circuits.[citation needed]
