Texas Instruments TMS320C6400

The TMS320C64xx is Texas Instruments fastest (currently) fixed point DSP family. It's part of the TMS320C6x DSP family, which is in turn part of the TMS320 family.

*It has 256 bit VLIW Very long instruction word based on VelociTI instruction set dual Harvard architecture.
*32 bit data word length
*Clock speed ranging from 300 - 1000MHz
*Code compatible with the older C6200 fixed point family and with the C6700 floating point family.
*The C64xx cpu has two sets of functional units. Each set contains four units and a register file of 32 32-bit registers. There is a cross path between the sets of functional units.
**M - All multiplication operations also include bit-count, rotate, Galois field multiplies, and bidirectional variable shift hardware.
**L - Logic and arithmetic operations - 32/40-bit arithmetic and compare operations and 32-bit logical operations
**S - Logic and arithmetic operations - 32-bit arithmetic operations , 32/40-bit shifts and 32-bit bit-field operations, 32-bit logical operations , Branches, Constant generation and Register transfers to/from control register file (.S2 only)
**D - Data addressing units - Address calculations, loads and stores, constant generation and 32 logical operationsFor more details +
*64 registers of 32-bit word length
* Capable of up to four 16-bit MAC (multiply-accumulates) per cycle or up to eight 8-bit MAC per cycle.
