FastMATH was a family of matrix and vector math processors with an on-die RISC CPUs introduced by Intrinsity. The chips were developed using Intrinsity's own proprietary Fast14 technology.

Architecture

Main article: FastMATH Microarchitecture

FastMATH was a series of microprocessors developed by Intrinsity using Fast14 technology - i.e. processors designed using custom dynamic domino logic. These chips incorporate the FastMIPS core along with a custom high-performance matrix and vector math coprocessor.

Matrix and Vector Math Processing Unit

The unit is designed as a single-instruction, multiple-data (SIMD) architecture capable of oeprating on 4x4 arrays of 32-bit values. Operates support fixed-point matrix, vector, and scalar data types with dedicated local register file. Data arrays are directly fetched from L2 cache.

• Zero-cycle latency, two-cycle throughput
• 64 GOPS (peak) at 2 GHz
• 551,000 radix-4 1024-point 16-bit FFTs/sec at 2 GHz
• 32 GMACs/sec at 2 GHz

This section requires expansion; you can help adding the missing info.
