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.

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™) ...

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 ...
