Arithmetic logic units (ALU) perform arithmetic and logic operations on binary data inputs. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU). In ...

In the 1970s CPUs still had wildly different approaches to basic features, with the Intel 8086 being one of them. Whereas the 6502 used separate circuits for operations, and the Intel 8085 a clump of ...

A computer is, at its core, just a bunch of transistors wired together. Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic Logic ...

Central Processing Unit (CPU) is the heart and brain of every computer. Every single operation that you do with your computer is processed in CPU. The performance of your computer is based on its ...

This chapter examines additional features of the PIC18Fxx2 instruction set architecture in the context of unsigned 8-bit arithmetic, bitwise logical, and shift operations. These operations are used to ...

The developing team at Arith-Matic a British computational hardware project and micro startup, have created a new 4-bit arithmetic unit, designed to be provided in kit form and “beautifully dissects ...
