Comsys Communication and Signal Processing has licensed CEVA’s CEVA-X1641 Quad-MAC DSP Core for its latest generation of WiMAX baseband processors. Comsys will use the CEVA DSP core for the computation-intensive baseband processing functions within its converged and multimode cellular/mobile WiMAX solutions.

Features include four simultaneous multipliers, a 128-bit data memory bandwidth and dedicated mechanisms such as dynamic and selective unit shutdowns and clock gating. As a result, the powerful DSP core is equipped to handle data rates up 100 Mbps with low power consumption, thus giving longer battery life for mobile handsets.

“The trend toward convergence of cellular and WiMAX technologies for handsets continues to build momentum, and Comsys is committed to enabling this convergence through the development of advanced baseband processors supporting current and future profiles,” said Ehud Reshef, product manager at Comsys. “The exceptional performance and the flexibility offered by the CEVA-X1641 DSP provides us with the platform to develop our multimode baseband processors addressing both current and future mobile WiMAX applications.”

Eyal Ben-Avraham, vice president of business development at CEVA, said, “By adopting our CEVA-X architecture for their WiMAX baseband processors, Comsys may re-use the same platform for next-generation standards such as 802.16e, 802.16m, 3GPP-LTE and additional evolving 4G standards.”

CEVA-X1641 is the first Quad-MAC DSP core in the scalable CEVA-X family and is designed specifically to run highly computation-intensive tasks that require substantial data throughput and high memory bandwidth. The core is fully synthesizable with enhanced memory architecture. This provides users with the flexibility to optimize memory size and structure for their specific application. Like other CEVA-X ISA-compliant cores, the CEVA-X1641 is a combined VLIW/SIMD architecture and also incorporates specialized video instructions and mechanisms to accelerate multimedia processing in applications like mobile TV and video conferencing.
