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 ...

Choosing a microcontroller is a matter of convenience, but it doesn’t have to be this way. There are dozens of different ARM cores alone, hundreds of 8051 clones, and weirder stuff including the ...
