The ConnX Baseband Engine is a configuration option package for Tensilca's Xtensa LX customizable processor core. It implements a 3-way VLIW, 8-way SIMD architecture that can sustain 16 multiply-add operations per second and performance of a full radix-4 FFT butterfly per cycle. At 400 MHz, it provides almost 13GM per second of memory bandwidth and 1.6B complex FIR filter taps per cycle. It directly implements 8-way parallel division and 4-way parallel reciprocal square root operations. And up to eight ConnX Baseband Engines can be used together for maximum performance.
The rich programming environment, including vectorization of scalar C applications, allows easy deployment of into complex applications. In addition, the Xtensa processor family, including the ConnX Baseband Engine, supports easy integration of multiple cores with high-bandwidth memory and direct port interconnect among each tightly-coupled cluster of cores.
The ConnX Baseband Engine is specifically designed for digital television, cellular basestation, femto-cell and other software-agile radio applications and is also being used to provide full programmability for multi-standard broadcast receivers.
