Texas Instruments TMS320C6400

The TMS320C64xx is Texas Instruments fastest (currently) fixed-point DSP family. It is part of the TMS320C6x DSP family, which is in turn part of the TMS320 family.
* It has 256-bit VLIW based on VelociTI instruction set dual bus Harvard architecture.
* 32-bit data word length
* Clock speed ranging from 300-1000 MHz
* Code compatible with the older C6200 fixed-point family.
* The C64xx CPU has two sets of functional units. Each set contains four units and a register file of 16 (C64x) or 32 (C64x+) 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 operations
For 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.
