Most 8-bit microcontrollers can handle limited, multibyte operations such as addition and subtraction through the use of subroutines and the arithmetic unit's carry flag. More complex operations ...

By provided the corresponding control unit, the proposed reversible ALU can combine the classical arithmetic and logic operation in a reversible integrated system. This letter provides actual evidence ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device.

My manager studied electrical engineering in Columbia in the early 90’s, and every student had to build an 8-bit TTL CPU. I wish modern American universities provided that depth in their curriculum.

Bit slice processors used arithmetic logic units (ALUs) that typically came in 4-bit increments, although 1- and 2-bit devices were also made. Connected to a control unit, ...

San Mateo, Calif. – Actel Corp. today will throw its hat into the microcontroller ring by introducing an 8-bit MCU platform for integration in its ProASIC Plus, Axcelerator, SX-A and ...
