The floating point unit in the synergistic processor element of a CELL processor is a fully-pipelined 4-way SIMD unit designed to accelerate media and data streaming. It supports 32-bit single-precision floating point and 16-bit integer operands with two different latencies, optimizing the performance of critical single-precision multiply-add operations. It employs fine-grained clock gating for power saving. Architecture, logic, circuits and integration are co-designed to meet the performance, power, and area goals.
