Xtensa LX3 - 10 GigaMAC/Sec DSP Performance, tops 1 GHz

The base Xtensa LX3 DPU configuration can reach speeds of over 1 GHz in 45nm process technology (45GS) with an area of just 0.037 mm² and power of 0.015 mW/MHz. When built with the new ConnX Baseband Engine DSP (ConnX BBE), the Xtensa LX3 processor delivers over 10 Giga-MACs-per-second performance, running at 625 MHz with a footprint of 0.93mm² (post place-and-route 45GS) and consuming just 170 mW (including leakage).
