"I wrote an 8051 CPU emulation core with complete instruction-set support. The core is fast and has been well tested. The Intel MCS-51 BASIC interpreter code runs perfectly as an example, see the example application below. " - Jean Nicolle

• The CPU core is fully emulated, all instructions.
• Interrupts are not emulated (which would be pretty easy to add).
• On-chip peripherals are not emulated (which would be much more complex to do completely and accurately)

Here are a few designs targeted for Altera's UP1-board. They are programmed using HDLs (AHDL, VHDL and Verilog HDL). These designs can be useful as demos for the UP1 board and HDL source examples. They emulate some old video games.

EdSim51 - 8051 Simulator

EdSim51 - 8051 Simulator

A virtual 8051 is interfaced with virtual peripherals such as a keypad, motor, display, UART, etc. The student can write 8051 assembly code, step through the code and observe the effects each line has on the internal memory and the external peripherals.

A Note from the Developer - jameswrogers.com .While lecturing in electronics at IT Sligo, I searched the Internet for an 8051 simulator suitable for teaching but to no avail. I therefore decided to develop my own simulator for the basic 8051 with virtual peripherals attached to the four ports. After about a year's working on the project, on and off, the result was the EdSim51 simulator. I then put together a set of notes that are now the Beginner's Guide to the 8051on this website.

The Virtual Peripherals:

• Analogue-to-Digital Converter (ADC)
• Comparator
• UART
• 4 Multiplexed 7-segment Displays
• 4 X 3 Keypad
• 8 LEDs
• DC Motor
• 8 Switches
• Digital-to-Analogue Converter (DAC) - displayed on oscilloscope

8051 Macro Assembler ASEM-51

8051 Macro Assembler ASEM-51

ASEM-51 is a two-pass macro assembler for the Intel MCS-51 family of microcontrollers. It is running on the PC under MS-DOS, Windows and Linux. The ASEM-51 assembly language is based on the standard Intel syntax, and implements conditional assembly, macros, and include file processing.

The assembler can output object code in Intel-HEX or Intel OMF-51 format as well as a detailed list file. The ASEM-51 package includes support for more than 180 8051 derivatives, a bootstrap program for MCS-51 target boards, and documentation in ASCII and HTML format. And it is free ...
