Linley Microprocessor Report: Ceva’s BX Hybrid Boosts DSP Engine

By Mike Demler (February 4, 2019).
Ceva’s new BX DSP cores offer upgrades to the first-generation X-series models, which employ a hybrid architec-ture combining multicore scalar CPUs for control functions with a highly configurable five-way SIMD/VLIW DSP en-gine for signal processing. The new intellectual property (IP) core tightens security by using a TrustZone-like memory subsystem to isolate secure applications from nonsecure ones. Architectural enhancements double the fixed-point DSP performance compared with the previous generation, and floating-point DSP operations receive up to an 8x boost….
