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.

Some people think that programs for microcontrollers like the 8051 that have limited program memory must be written in assembly language rather than a high-level language like C. The executable code ...

Suppose for a moment that you're an engineer designing a new 8051-based product. Not unexpectedly, the application's code size will greatly exceed the 64KB architectural limit of the 8051's program ...
