now offers a debugging solution for 8051 IP cores that requires a single connection instead of the four needed for traditional JTAG debug. The new Single-Wire On-chip Rapid Debugging (SWORD™) ...

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.

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 ...

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 ...
