jnicolle.com – 8051 – Altera HDL UP1
“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.

KD7LMO amateur radio and open source hardware
Nixie Tube Clock
“In the pioneering sprit of amateur radio and open source hardware and software, I’ve assembled a collection of information and engineering plans for a variety of amateur radio projects. These projects cover a wide range of disciplines.” – KD7LMO
From the GNU radio web site
“GNU Radio is a collection of software that when combined with minimal hardware, allows the construction of radios where the actual waveforms transmitted and received are defined by software.
What this means is that it turns the digital modulation schemes used in today’s high performance wireless devices into software problems.”
The latest in SDR (Software Defined Radio) technology. Here are some projects and information that rely on the GNU Radio and USRP (Universal Software Radio Peripheral).

“The DIY of designing and building of your own equipment is not only very satisfying as hobby on itself, but it will save you money, which you can invest in better parts used or parts you cannot build yourself like Turntables, cartridges etc.”
