Implementing a single-processor cellular modem on an SC1000-family core

Abstract

The much-heralded concept of creating a single-processor cellular modem has now become reality. TTPCom's latest version of their cellular baseband engine (CBE 2000) combines both digital signal processor and microcontroller functions on a single processor, resulting in a greatly simplified programming model. This provides a more flexible way to partition tasks for easier maintenance and higher programming efficiency. In this paper, we present an innovation that demonstrates a new system architecture. StarCore's VLES (variable-length execution set) technology allows software developers to develop both signal processing and control code entirely in C and compile it into a seamlessly integrated application.
