To achieve the ambitious goals, the company ventured into development of full-custom LSI chips : a 4-bit slice arithmetic logic unit and 3-chip control unit.

In systems without any floating-point hardware, the CPU emulates it using a series of simpler fixed-point arithmetic operations that run on the integer arithmetic logic unit.
23.
It has eight execution units : two arithmetic logic units ( ALUs ), two double precision floating-point units, two load / store units and two AltiVec units.
24.
Using a one-bit serial arithmetic logic unit ( ALU ) implementation, allowed the PDP-8 / S to be smaller, less expensive and slower than the original PDP-8.
25.
For execution, the FXU contains the POWER1's fixed-point register file, an arithmetic logic unit ( ALU ) for general instructions, and a dedicated fixed-point multiply and divide unit.
26.
The 7400 series contains hundreds of devices that provide everything from basic logic gates, flip-flops, and counters, to special purpose bus transceivers and arithmetic logic units ( ALU ).
27.
Each functional unit is not a separate CPU core but an execution resource within a single CPU such as an arithmetic logic unit, a bit shifter, or a multiplier.
28.
The hardware that operates during this stage is contained in the EBOX, which comprises the register file, arithmetic logic unit ( ALU ), barrel shifter, multiplier and condition code logic.
29.
Parts of the machine were up and running quickly, with the math and logic units ( the arithmetic logic unit in modern terminology ) running by the autumn of 1950.
30.
For example, a divide-by-zero exception will be thrown if the processor's arithmetic logic unit is commanded to divide a number by zero as this instruction is in error and impossible.
