NeuroMatrix® NM6404 DSP 
NeuroMatrix® NM6404 is a high performance DSP oriented RISC processor designed for real time data flow processing. The architecture is based on advanced VLIW/SIMD NMC2 core and includes two main units: 32/64-bit RISC and patented 64-bit VECTOR co-processor. This co-processor supports vector operations with elements of variable bit length. NM6404 has 2Mbit on-chip memory to enhance the system performance, two 64-bit interfaces with 1.28Gbyte/sec throughput, two high-speed byte ports up to 60Mbyte/sec throughput, a JTAG port and two 32-bit timers.
