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
