# NeuroMatrix

NeuroMatrix is a digital signal processor (DSP) series developed by NTC Module. The DSP has a VLIW/SIMD architecture. It consists of a 32-bit RISC core and a 64-bit vector co-processor. The vector co-processor supports vector operations with elements of variable bit length (US Pat. 6539368 B1) and is optimized to support the implementation of artificial neural networks. From this derives the name NeuroMatrix Core (NMC). Newer devices contain multiple DSP cores and additional ARM or PowerPC 470 cores.
