DSP Cores for Audio, Voice, and Baseband Applications
CEVA-TeakLite family use cases
Digital signal processing is a key technology that is powering many of today’s fastest growing electronics markets. CEVA is the world’s leading licensor of programmable DSP cores and Platforms and Solutions.
The CEVA-TeakLite Family of DSP cores is designed to address the needs of high volume, cost-sensitive markets, and has been adopted by over 75 licensees and shipped in more than 2 billion devices to-date. Founded on a classic memory-based Harvard architecture, with 16-bit or 32-bit data word-widths and single, dual or quad MACs, the CEVA-TeakLite family combines small die size, excellent code density, and high processing power.
Which CEVA-TeakLite DSP core is right for me?
True 32-bit DSP architecture framework ideal high-performance, low-power audio processing and voice processing applications.The high-performance, low-power, low-cost fully synthesizable native 32-bit CEVA-TeakLite-4 DSP architecture is ideal for the widest range of audio and voice processing applications. The CEVA-TeakLite-4 is fully compatible with its predecessors, including the widely adopted CEVA-TeakLite, CEVA-TeakLite-II, and CEVA-TeakLite-III DSP cores. This allows new designs to leverage existing applications and a large installed base of software; it also makes it easy for existing designs to be migrated to a higher performance core.
The CEVA-TeakLite-4 architecture is initially available as a series of four compatible DSP cores, offering designers a range of application-specific cost/performance alternatives to meet their application requirements.
Target applications for the CEVA-TeakLite-4 DSP cores are primarily audio and voice processing in mobile, home, and automotive products in chips ranging from the smallest, lowest-power audio CODECs, to application processors, to home audio, including digital televisions (DTVs), set-top boxes (STBs), game consoles, and more.
True 32-bit DSP ideal for high-end audio processing, voice processing and baseband applications.The high-performance, low-power, low-cost fully synthesizable dual-MAC native 32-bit CEVA-TeakLite-III DSP engine is ideal for high-end audio and voice and wireless baseband applications. The CEVA-TeakLite-III is fully compatible with its predecessors, including the widely adopted CEVA-TeakLite and CEVA-TeakLite-II DSP cores. This allows new designs to leverage existing applications and a large installed base of software; it also makes it easy for existing designs to be migrated to a higher performance core.
The CEVA-TeakLite-III DSP engine forms the basis of two implementations: the CEVA-TL3210 and CEVA-TL3211 DSP cores. The CEVA-TL3210 offers a wealth of high-end features including a configurable L1 program cache memory and support for industry-standard APB and AHB-Lite system busses. The CEVA-TL3211 offers configurable L1 program and data cache memories, support for high-speed AXI system busses, and an integrated Power Scaling Unit (PSU).
Target applications include HD audio, HD voice, 2G/2.5G/3G wireless baseband, VoIP, Power Line Communication (PLC), and other signal processing for home entertainment (DTV, STB, Blu-ray), mobile computing devices, wireless handsets, portable media players, hard disk drives, optical drives, and more.
Enhancing its predecessor with larger memory, higher frequency, and more interfaces. The CEVA-TeakLite-II is a low-power, single MAC, 16-bit, fixed-point DSP core that has been specifically designed to be embedded in highly-integrated System-on-Chip (SoC) devices. It extends the CEVA-TeakLite’ feature set with larger program and data memory spaces, higher frequency, and standard memory interfaces.
The CEVA-TeakLite-II is binary compatible with its predecessor, the widely adopted CEVA-TeakLite DSP core. This allows new designs to leverage existing applications and a large installed base of software; it also makes it easy for existing designs to be migrated to a higher performance core.
The capabilities of the CEVA-TeakLite-II DSP core are augmented by the Xpert-TeakLite-II sub-system, which incorporates a variety of advanced features including on-chip instruction cache and data memories, a high- performance Direct Memory Access (DMA) controller, Buffered Time Division Multiplexing Ports (BTDMPs), standard AMBA bridges (AHB and APB), and other peripherals such as Timers, Host interface, and GPIO ports.
Target applications include audio, voice, 2G/2.5G wireless baseband, VoIP, Power Line Communication (PLC), and other signal processing for mobile computing devices, wireless handsets, portable media players, hard disk drives, optical drives, and more.
Most cost and power efficient DSP specifically designed to be embedded in highly-integrated SoCs. The CEVA-TeakLite is a low-power, single MAC, 16-bit, fixed-point DSP core that has been specifically designed to be embedded in highly-integrated System-on-Chip (SoC) devices.
