X86

The 8086 Processor A Brief History The Intel 8086, released in 1978, marked a pivotal moment in computing history as Intel’s first 16-bit microprocessor. Designed by a team led by Stephen Morse, the 8086 was Intel’s answer to the growing demand for more powerful processors that could handle larger programs and address more memory than the existing 8-bit chips of the era. The processor introduced the x86 architecture that would become the foundation for decades of computing evolution. With its 16-bit registers and 20-bit address bus 1, the 8086 could access up to 1 megabyte of memory—a massive improvement over the 64KB limitation of 8-bit processors. However, it retained backward compatibility concepts that would prove both beneficial and constraining for future generations. ...
