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.

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 ...

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...

A myriad of sophisticated control systems are emerging with demanding requirements for high-speed precision digital and analog performance. Cygnal Integrated Products addresses these demands with a ...
