ARM Prime

Nick Craig-Wood — Mon, 01 Jan 0001 00:00:00 UTC

A Mersenne prime tester for ARM processors
by Nick Craig-Wood

This is the home page for my ARM Prime program. This is for testing for Mersenne prime numbers on StrongARM machines for the GIMPS project. The program is work in progress, but if anyone is interested in using or helping to develop the program then please drop me an e-mail to nick@craig-wood.com.

At present I haven't released the program formally, because it needs a few vital features added (like save files). However it does work and has contributed a few results to GIMPs already. (See the to do list for further deficiencies!)

As for speed ARM prime is will be about 1/3 of the speed of an equivalently clocked Pentium. This is because the StrongARM does not have a floating point unit. This also means that ARM prime has been written to use an all integer FFT/DWT which makes it a bit different as explained in the math section.

Cocker Spaniel Now: Holly

Nick Craig-Wood — Mon, 01 Jan 0001 00:00:00 UTC

Holly was our Cocker Spaniel. She was a loving dog but a little bonkers! There was nothing she enjoyed more than howling along while we were singing, or eating socks. Unfortunately Holly is no longer with us, having chased a rabbit off a cliff at the fine old age of 14. Here are some pictures of that much loved dog.

ISTEC 1008

Nick Craig-Wood — Mon, 01 Jan 0001 00:00:00 UTC

This page is of historical interest only. I put these pages up for the enjoyment of all I don't sell or deal in ISTECs - you will have to look elsewhere for that.

The economical and easy to use ISDN private exchange

Summary of the features

1 S0 interface to the public network
8 analogue a/b interfaces
Door intercom interface
Pulse / Tone dialling
1 RS232 interface for setup / billing
Configuration software
Charge metering
Call transfer
Inquiry call
Internal 3-way conference
Broker call
Call pick up
Music on hold
Call barring (call number blocking)
4 Classes of external call authorization
External call rerouting
Internal call rerouting
Pickup from answering machine
Selectable service ID for each line
Direct dialling to each extension
Free assignment of MSN and grouping
General access transfer
Protocol E-DSS1/1TR6 PTMT or PTP

The ISTEC 1008 is an easy to use digital communication system developed especially for small offices, such as tax consultants, lawyers, engineers, self employed,......., and also for the modern home.

The private exchange provides an economical way to operate analogue terminal equipment on an ISDN S interface. The a/b interfaces enable the operation of any conventional certified terminal equipment such as Group 3 Fax machines, modems, answering machines, and both cordless and other telephones on the ISDN network.

The ISTEC 1008 detects which dialling mode - DTMF tone or pulse - is used on the a/b interfaces. The system can operate with either EURO-ISDN protocol (DSS1) or the German 1TR6 protocol, and can be used on either an S bus or ISDN PBX line.

A few of the especially user friendly features are the direct dialling of extensions, selectable service ID for each extension, the easy to use configuration software, and also the rerouting of both internal and external calls.

The ISTEC 1008 consists of a central unit in a plastic case with 8 a/b interfaces, a standard network connection cable, and an external power supply. The system is ready for use on the ISDN network without any special setting up, in three easy steps: 1, connect the power supply cable: 2, connect the network cable to the ISDN socket: and 3, connect the analogue terminal equipment........

This is JohnRoids. A simple but addictive game whose sole purpose is to kill John.

I wrote this game originally in 1991 on my Acorn Archimedes to annoy John when I was bored one rainy afternoon. John came round and instead of being annoyed played the game for hours and hours - there is obviously some kind of perverse thrill in shooting oneself!

Back in 1991 digitised pictures were still something of a rarity. I made the one of John from a camcorder video and an extremely hacky black and white video digitiser which I built myself. Note there are actually two images of John - one looking happy and the other not!

The original was written entirely in ARM assembler to make it go fast enough. However I thought the program deserved not to wither away so in 2001 I ported it to C and SDL and in 2018 ported it to Go to run in the browser so many more hours can be wasted shooting at John.

When you run the game you'll notice the playing area is rather small (320x256 pixels). I'm afraid this was all that was available in 1991! I tried making the playing area bigger but the game lost some of its visceral thrill, so you are left with a small screen. If you want it bigger use the zoom function of your browser.

This is an entirely faithful conversion of the original except for the fact that I haven't put the sound back in yet. The original samples are in a very strange format I haven't managed to translate.

You can find the source code on github - report issues and send fixes there please!

The instructions are printed on the screen to start, but to summarise they are:

Z      - Rotate left
X      - Rotate right
Shift  - Fire thruster
Return - Fire gun
Space  - Start the game

If you press "Toggle Keyboard" you'll get an onscreen keyboard which works pretty well on mobile devices.

Shoot everything before it touches you. Note that you lose a point of score for every bullet you fire. Some of the roids may shoot at you - using thrust is a good idea at this point. Things get very hectic as you go through the levels.

Enjoy

NCWs Animations

Nick Craig-Wood — Mon, 01 Jan 0001 00:00:00 UTC

Here are some animations that I knocked up one rainy afternoon. The computer generated animations I made using my ancient and venerable juggling program. I captured the frames to a file and then used ChangeFSI to make them smaller with anti-aliasing. I then used InterGIF to produce the animation.

When making the men juggling men etc animations I made a small mistake which made the smaller men juggle at twice the rate of the larger men. This halves the quality of the smaller men's animation, but I left it because I rather liked the smaller men juggling faster the smaller they got.

The animation of Dave Lawrence was made from some video footage I took of him quite a few years ago now. It was captured with a ReplayDIY card, made into a Replay movie, then made back into frames (some years later) with a bit of bodge up BASIC, motion compensated (the original movie had a slight pan in it) and looped with another bodge up BASIC program, made smaller with ChangeFSI and made into an animated GIF with InterGIF (phew!).

Who am I?

An enigma wrapped up in a mystery? I used to have lots more stuff here but I got bored of it ;-)

What do I do?

Currently I'm doing about 17 different things. See below for list of current employers. I also have 4 children and a wife which need lots of attention :-)

What do I do for fun?

Hack on Go stuff, rclone or other cool stuff like gpython, play with the children, read books, walk the dog, mess about with Ham radio. When I have time (which isn't often) I watch TV.

In 2009 I gave up my beloved Nokia Communicator and moved on the the exciting world of Android. Being a software developer Android immediately enticed me in to start creating applications - something Symbian had never managed to do. Below you'll find the results!
