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
Floating point
In computing, floating point describes a method of representing real numbers in a way that can support a wide range of values. Numbers are, in general, represented approximately to a fixed number of significant digits and scaled using an exponent. The base for the scaling is normally 2, 10 or 16...

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
