This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.

As you may recall, in my previous column, I started to consider why the 30-year-old eight-bit 8051 microcontroller remains a valuable player in the embedded systems game. The days, months, and years ...

Editor's Note: View the Fundamentals of Microcontrollers to catch up on the architectural differences, selection, set up and programming of today's micros. To work through the thicket of choices, it's ...
