The CEVA-Teak is a 16-bit fixed-point general-purpose DSP core. Incorporating Dual MAC Architecture, It features: High-performance, high flexibility and throughput for complex Digital Signal Processing implementations.
The core is specifically designed for low-power, speech and audio processing, multimedia and wireless communications (GSM, CDMA, EDGE, GPRS, 3G, etc.), high-speed modems, advanced telecommunication systems, and various embedded control applications. CEVA-Teak is designed with consideration for low-power consumption so as to achieve the best possible performance with the lowest possible power consumption. It makes the core suitable to a wide variety of battery-powered portable applications.
The CEVA-Teak DSP core is backward compatible with the CEVA-TeakLite, CEVA-Oak, and CEVA-Pine. The CEVA-Teak is fully synthesizble ('soft core') and is process independent designed. It is easly portable to any ASIC library. The core is designed to be used as an engine for DSP-based Application Specific ICs (ASIC), and is available as a DSP core in a standard cell library, To be utilized as a part of the user's custom chip design. As such, it provides several levels of modularity in RAM,ROM and I/O, allowing efficient DSP based ASIC development. The core is designed in a single edge clocking system which allows the use of full or partial scan testing methodologies. The core supports Emulation, Debugging and Testing via JTAG.
- Soft Core (process and library independent).
- Low Voltage operation, down to one volt
- Low power consumption Three modes of operation:
- Active mode
- Slow mode - linearly reduces clock speeds and current consumption by a factor N (user defined factor)
- Stop mode - leakage current only
