Tensilica Cuts ConnX Current

摘要

Instead of escalating the war for multiply-accumulate (MAC) dominance, the newest ConnX DSP battles for energy efficiency while reducing programmable performance by 50%. To save power in wireless handsets, the BBE32UE offloads more of the DSP workload to hardware accelerators. Tensilica has been the DSP math champion, boasting 128 18x18-bit MACs per clock cycle with its ConnX BBE64-128 baseband processor (see MPR 5/16/11, "Xtensa Extends Instructions to 128 Bits").
