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 8051 featured a still reasonably respectable ... today until you realize this 30-year-old chip has 32 IO pins. This microcontroller, along with its bigger brother the 8052, served as the ...

The new Single-Wire On-chip Rapid Debugging (SWORD™) interface for the R8051XC2™ microcontroller core connects the 8051 to its debugging unit with just one IC debug port. The popular Joint Test Action ...

Normally, this isn’t huge news. The 8051 is the most copied microcontroller on the planet, and there are probably billions produced each year. Cheap parts are only cheap if your time is free ...
