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 bus Harvard architecture.
32 bit data word length
Clock speed ranging from 300 - 1000 MHz
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 operations

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.
