Advanced VLIW CPU with eight functional units, including two multipliers and six arithmetic units 2. Instruction packing 3. Conditional execution of most instructions 4. Efficient code execution on independent functional units 5. 8/16/32-bit data support, providing efficient memory support for a variety of applications -bit arithmetic options add extra precision for vocoders and putationally intensive applications 7. Saturation and normalization provide support for key arithmetic operations 8. Field manipulation and instruction extract, set, clear, and bit counting support mon operation found in control and data manipulation applications additional features of the C6000 : 1. Each multiplier can perform two 16 ?? 16-bit or four 8 ?? 8-bit multiplies every clock cycle 2. Quad 8-bit and dual 16-bit instruction set extensions with data flow support 3. Support for nonaligned 32-bit (word) and 64-bit (double word) memory accesses communication-specific instructions to address common operations in error-correcting codes 5. Bit count and rotate hardware extends support for bit-level algorithms 6. Compact instructions: common instructions (AND, ADD, LD, MPY) have 16-bit versions to reduce code size 7. Protected mode operation: a two-level system of privileged program execution to support higher capability operating systems and system features, such as memory protection 8. Exceptions support for error detection and program redirection to provi
