Abstract :
High-throughput parallel SIMD vector computations are the most performance and power-critical operations in multimedia, graphics and signal processing workloads. An array of SIMD vector processing engines delivers high- throughput short bit-width arithmetic operations on large data sets with orders of magnitude higher energy efficiencies vs. general-purpose cores. A reconfigurable 4-way SIMD engine targeted for on-die acceleration of vector processing in power-constrained mobile microprocessors is fabricated in 45 nm high-K/metal-gate CMOS.
