6.1.1 - Features
6.1.1.1 - Enhanced Addressing Capabilities
– New addressing modes including a double indi-
rect addressing mode with pointer post-modifi-
cation.
– Parallel Data Move: this mechanism allows one
operand move during Multiply-Accumulate in-
structions without penalty.
– New transfer instructions CoSTORE (for fast ac-
cess to the MAC SFRs) and CoMOV (for fast
memory to memory table transfer).
6.1.1.2 - Multiply-Accumulate Unit
– One-cycle execution for all MAC operations.
– 16 x 16-bit signed/unsigned parallel multiplier.
– 40-bit signed arithmetic unit with automatic sat-
uration mode.
– 40-bit accumulator.
– 8-bit left/right shifter.
– Full instruction set with multiply and multiply-ac-
cumulate, 32-bit signed arithmetic and compare
instructions.
6.1.1.3 - Program Control
– Repeat Unit: allows some MAC co-processor in-
structions to be repeated up to 8192 times. Re-
peated instructions may be interrupted.
– MAC interrupt (Class B Trap) on MAC condition
flags.
