Octasic Inc. has introduced its first SDR platform for GSM, EDGE, and EDGE Evolution BTS applications. Vocallo BTS, which is on display at the 2009 GSMA Mobile World Congress in Barcelona, Spain, employs a multicore, clockless DSP architecture, which allows users to create a range of next-generation, multistandard wireless solutions based a true SDR implementation, according to Octasic.

The Vocallo BTS Digital Signal Processor integrates a complete Layer 1 baseband for up to 12 GSM carriers or six EDGE carriers or any combination. All this is achieved in a 15- by 15-mm BGA package consuming less than 1 W (or 80 mW per carrier). The device’s impressive power density figure is a direct result of Opus, Octasic’s asynchronous DSP core technology. Elimination of the clock tree also brings benefits in chip size, enabling Vocallo BTS to be priced very competitively on a per carrier basis.

The product is fully supported by Opus Studio, the company’s intuitive graphical IDE, which provides the product with a full suite of Layer 1 GSM, GPRS, and EDGE modules. These modules are available as a 3GPP-compliant, source code reference library. Demonstrating both the efficiency of the toolset and the control capability of the DSP, reduced Layer 2 and Layer 3 code also runs on Vocallo BTS.
