Tensilica DSP Targets LTE Advanced

Tensilica DSP Targets LTE Advanced

Written by the independent writers at Linley Group's Microprocessor Report, this document reviews Tensilica's ConnX BBE64.

Cellular networks delivering 1Gbps of raw data throughput are on the horizon, and Tensilica is designing a DSP to meet the baseband-processing requirements of such networks: the ConnX Baseband Engine 64 (BBE64). The BBE64 achieves its performance by employing wide execution units that support up to 128x 18-bit operations in parallel, wide 640-bit registers, and massive I/O. The company targets a performance increase of 5-15 times for the BBE64 compared with the currently availablwe BBE16 for LTE.
