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.

EX-CommandStation firmware from DCC-EX. Includes support for WiFi and a standalone WiThrottle server. A complete re-write of the original DCC++.

Ted Fried's MicroCore Labs Projects which include microsequencer-based FPGA cores and emulators for the 8088, 8086, 8051, 6502, 68000, Z80, Risc-V, and also Typewriter and EPROM Emulator projects.

While 8 or 16-bit MCUs, such as 8051 and 80251 microcontrollers, can be sufficient for entry level edge objects with minimum security, more and more IoT objects with embedded RTOS and upgradable ...

This little box remembers all of your user names and passwords. Inside you’ll find an Atmel AT89S5131 microcontroller which has built-in USB capability. When the box is plugged into a USB port ...
