Udi's Homepage

What is this all about? Yet another stupid Homepage?

Well, actually, yes.
You won't find my picture and my bio there, though. This homepage is not that stupid.

Then why am I doing this?

Mainly to learn HTML, and to publish some of the neat hacks and tools I have done over the years. Most of them related to programming and digital hardware design.

Don't expect any fancy graphics, animations, frames or other bells and whistles! (Well, we actually got some frames now, but that's just because I wanted to learn how to use them!)

PCISIM

PCISIM is both a logic simulation library and a PCI simulation environment coded using the simulation library. It can be used as a stand-alone logic simulation library, or as a complete PCI simulation environment by using the PCI models included.

FMV

FMV, or File Majority Voter, is a small utility used for DAE (Digital Audio Extraction). It will take N sample files, and construct one output sample file. For every byte position in the output file, the program will look at the corresponding bytes in the input files, and select the most common input value as the output value.
This program is great for cleaning DAE sample files, since some CDROM drives produce samples with random noise, which is usually not repeated in the same byte position, on repeated sampling. This way, sampling multiple copies of the same DAE data, and running them through the program, will clean the bad samples which will be thrown out since they will be "voted out" by the majority of the "good" samples in the other files.

Here is a link to the code. Documentation is too obvious to bother writing. No command line flags, just one output file, and any number of input files.

CDDUP

CDDUP is based on the same core as FMV, but is intended for direct audio extraction from CD's. It requires DAO as the DAE engine though. CDDUP will sample N copies of each audio section, clean it, save it to disk, and advance to the next section.

Here is a link to the documentation.

Here is a link to the code. It compiles under Visual C++ 5.0.

DAO is a commercial software package, available from GoldenHawk software

Win32 GTKWave

This is a straightforward port of GTKWave to Win32. GTKWave is a VCD/EVCD waveform viewer. If you don't design hardware using VHDL or verilog, you shouldn't be interested by this.

PUNTO

PUNTO is a Perl script that is planned to grow into some sort of "swiss army knife" for PCB netlists. For more details about PUNTO and what it can do, please visit the PUNTO homepage.

Home made, ST-02 based, DiskOnChip 2000 programmer.

Just what the title says. If you have an old ST02 card lying around, you could turn it into an M-Systems D.O.C 2000 programmer.
