Computation Unit

The all-zero values are necessary for data transfers and unitary operations. All-zeros also serve as default values for the registers, which helps to minimize residual power consumption. The databus path through ALU-A is used to input memory values (RAM) and constant values (program memory) to the ALU. The PH and PL inputs are useful for supporting multiply-accumulate operations (refer to Section 2.2.1, Multiplier).

The operations supported by the ALU include arithmetic, logic, and comparison. The arithmetic operations are addition, subtraction, and load (add to zero). The logical operations are AND, OR, XOR, and NOT. Comparison includes equal-to and not-equal-to. The compare operations may be used with constant, memory, or string values without destroying any accumulator values.

2.2.2.1Accumulator Block

The output of the ALU is the accumulator block. The accumulator block is com- posed of 32, 16-bit registers. These registers are organized into two terminals, denoted accumulator and OFFSET accumulator. The terminals provide refer- ences for all of the data which is to be held in the accumulator block. The accu- mulator incorporates one-half of the 32 accumulator registers: AC0..AC15. The OFFSET accumulator incorporates the other half: AC16..AC31.
