CEVA-TeakLite-II DSP core is a low power, single Multiply-Accumulate (MAC), 16-bit fixed point DSP core, designed specifically for embedded and highly integrated System-on-Chip (SoC) designs. At a speed of 200MHz for a TSMC 0.13u G worst case process, voltage and temperature, the TeakLite-II performance, cost and power consumption presents an attractive metric that is attractive to emerging high volume applications in the consumer and wireless fronts.
CEVA-TeakLite-II is binary compatible with its predecessor DSP generations, the widely adopted CEVA-TeakLite and CEVA-Oak DSP cores, allowing its users to leverage on the existing applications and large installed base of software available for these products and easy migrate it to a higher performance DSP.
CEVA-TeakLite-II is a fully synthesizable (Soft Core), process independent design, allowing customers to select the optimal operating point in terms of silicon area, power consumption and frequency. The DSP can be easily ported to any foundry process and library, enabling licensees full control over fabrication costs.
CEVA-TeakLite-II core has an advanced set of Digital Signal Processing instructions as well as general microprocessor functions. The core's programming model and instruction set are designed for straightforward generation of efficient and compact code composed of 16-bit wide instructions. TeakLite-II integrates run time debug functionality useful for field updates and remote fault detections and supports various memory configurations, including RAM, ROM and system peripherals such as DMA, timers, serial ports and bus interfaces.
