- Reverse-engineering the 8086’s Arithmetic/Logic Unit from die photos (righto.com)
The Intel 8086 processor was introduced in 1978, setting the course of modern computing. While the x86 processor family has supported 64-bit processing for decades, the original 8086 was a 16-bit processor. As such, it has a 16-bit arithmetic logic unit (ALU).1 The arithmetic logic unit is the heart of a processor: it performs arithmetic operations such as addition and subtraction. It also carries out Boolean logic operations such as bitwise AND and OR as well as also bit shifts and rotates. Since a fast ALU is essential to the overall performance of a processor, ALUs often incorporate interesting design tricks.
