CEVA-HD-Audio is a DSP-based single-core audio platform targeting high-volume ICs for devices such as Blu-ray Disc players, DTVs and home entertainment systems.
CEVA-HD-Audio combines several CEVA-developed technologies including the CEVA-TeakLite-III™ DSP core, a configurable cached audio subsystem, a comprehensive set of optimized HD audio codecs, and complete software development kit, including software development tools, prototype boards, systems drivers and RTOS. This complete solution, fully developed and maintained by CEVA, ensures quick and easy development and integration into the customer's SoC.
Programmable DSP Engine - a 550MHz CEVA-TeakLite-III is a high performance, yet small die size and low-power DSP core, optimized for audio processing
Configurable Memory Subsystem - the CEVA-TL3210, a highly integrated, compact DSP subsystem, incorporating a CEVA-TeakLite-III core, a configurable cached memory architecture with a small memory footprint, an optional DMA engine for efficient data transfers, and an AMBA standard bridges for easy system integration
Audio Software - CEVA's open, programmable platform contains a comprehensive set of industry standard audio, speech and voice codecs, optimized for the CEVA-TeakLite-III DSP, taking into consideration typical audio system limitations
Complete Software Development Kit (SDK) - a complete software development suite, including development tools, development boards, software system drivers and RTOS, for easy application development and system integration from initial design through final tape-out
