The Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete.

Internally, the Efficeon has two arithmetic logic units, two load / store / add units, two execute units, two floating-point / SSE / SSE2 units, one branch prediction unit, one alias unit, and one control unit.

Building on 8-bit arithmetic logic units ( 3800 / 3804 ) he designed earlier at Fairchild, in 1969, Lee Boysel created the Four-Phase Systems Inc . AL-1 an 8-bit CPU slice that was expandable to 32-bits.

To execute quickly, operands of the arithmetic logic unit ( ALU ) may be the top two registers of the stack and the result from the ALU is stored in the top register of the stack.
46.
Perhaps the most obvious examples were the bit-addressable memory, the variable size arithmetic logic unit ( ALU ), and the ability to OR in data from a register into the instruction register allowing very efficient instruction parsing.
47.
The machine ran at a clock speed of 1 MHz and its arithmetic logic unit ( ALU ) operated on data in a " serial-parallel " fashion the 48-bit words were processed sequentially four bits at a time.
48.
Another unusual feature was that rather than execute mask, rotate, shift and merge instructions in the arithmetic logic unit ( ALU ), as is the case with most microprocessors, the 8X300 had separate mask, rotate, shift and merge units.
49.
However, certain processor features tend to lead to designs that have higher-than-average IPC values; the presence of multiple arithmetic logic units ( an ALU is a processor subsystem that can perform elementary arithmetic and logical operations ), and short pipelines.

The computer was the first fault-tolerant computer it had three parallel arithmetic logic units, which decided on the correct result by voting, an example of triple modular redundancy ( if all three results were different, the operation was repeated ).
