Abstract :
A 32 nm on-die fine-grained reconfigurable fabric for DSP/media accelerators is fabricated and occupies a 0.076 mm2 die. The optimized hybrid arithmetic configurable logic blocks with self-decoded look-up tables, ultra-low voltage PVT-tolerant register file circuits and dual-supply operation help enable a 2.4 GHz nominal performance at 1.0 V and 320 mV-to-1.2 V dynamic voltage range. The peak energy efficiency is 2.6TOPS/W when measured at 340 mV and 50°C.
