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.

The latest improvements to this industry standard guarantee the fastest average instruction execution in the 8051 market. Gliwice & Bielsko-Biala, Poland -- January 26, 2009 - The Silicon Intellectual ...

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 ...
