Jack Whitham: May 2015
http://blog.jwhitham.org/2015_05_01_archive.html
Sunday, 3 May 2015. Review: UndoDB, a reversible debugger. This is a review of a reversible debugger. It's a debugger for Linux, with GDB compatibility, which means it is a drop-in replacement for debugger frontends on the Linux platform (e.g. Eclipse, DDD, and also the IDE I use at work. Which is GNAT Programming Studio. Like recent versions of GDB, it is able to "run" code backwards. Like features provided by IDEs, or the invaluable error-detection capabilities of Valgrind. I first saw a reversible deb...

Thursday, 30 May 2013. Users of email will not put up with it". If you have ever used email, then you will know about spam, or unsolicited bulk email. You may also know that various intelligent and technical people have proposed solutions to deal with it: solutions that they invariably believe to be clever and novel. However, the solutions usually turn out to have some practical flaw which makes them unworkable. Was created as a generic response. It begins like this:. Your post advocates a. It is therefo...
Jack Whitham: April 2015
http://blog.jwhitham.org/2015_04_01_archive.html
Sunday, 26 April 2015. Relative speed of Raspberry Pi, Pi 2, and desktop PC (x86 and AMD64). Posts described my attempts to build a benchmark program from the Quake 2 source code, to complement a similar program I made. From the Doom source code. The main issues have been related to floating-point numbers; much of the effort has gone into discovering why the rendered output from Quake 2 was slightly different with different GCC configurations, different CPUs and different math libraries. Both benchmarks ...

Monday, 15 April 2013. BurchEd B3 and B5 FPGA boards; reminisces and documentation. The first FPGA board that I ever used was a BurchEd B5. I used it to build a CPU. Not a very good one, but my first, and it worked. This was during 2002-2003; it was my third-year undergraduate project. BurchEd B5 FPGA board. I set out to find the documentation for this board, and discovered that it is no longer on the web. BurchEd is no longer in business, and the documentation is gone, having disappeared with BurchE...
Jack Whitham: October 2013
http://blog.jwhitham.org/2013_10_01_archive.html
Sunday, 20 October 2013. If you are ripping a CD, and compressing the music for storage on your computer or portable player, what bitrate setting is enough? I am writing about " lossy compression. Software is used to process music files on a CD, removing parts of the sound that are (theoretically) inaudible, so that the music can be stored in less space. MP3, AAC and Ogg Vorbis are examples of lossy compression formats, and my portable player. Too high, and space is wasted, on the hard disk and on the po...

The virtual lab provides a remote FPGA. The manual for the virtual lab. Is now online. Some of the software, such as client libraries, can be downloaded. The virtual lab uses the following software:. An embedded system based on Linux software. FPGA hardware. This acts as an interface between a TCP/IP network and an FPGA board, allowing the board to be programmed and controlled using a serial protocol. I modified the Linux kernel. For this device and wrote the embedded application.

Is legacy research software. It's not a good idea to use it for new projects, PhD work or taught courses. However, it has been used quite widely in the past. It remains important enough to still receive occasional maintainance updates. Unfortunately, these only include the two simulation targets supported by Simplescalar version 3.0, namely PISA and Alpha. Though maintenance release 3.0e will compile on current Linux systems (as shown in this video. The required version of gcc appears to be 3.2. ...Users...

Including Blue Jam, On The Hour and The Day Today. While his appearances on The Day Today and On The Hour tended to be short announcements, he provided much longer segments for Blue Jam and the Chris Morris Radio 1 Music Show. These surreal "dance charts" and "news" broadcasts were a perfect fit for his RP. In order of appearance:. Gone are...

Real-time Processor Architectures for Worst Case Execution Time Reduction. I submitted my PhD thesis in January 2008, and my minor corrections were accepted four months later. The thesis deals with the problem of building computers that (1) complete their tasks within a guaranteed period of time (" hard real-time. The part of a computer that runs programs. I found a way to implement a CPU design that combines predictability with performance, and then used WCET. Instances of the new architecture class are...

The Silicon Emperor
Thoughts on technology and life, from Baltimore, Maryland. Friday, November 1, 2013. The patent reformation working it's way through Washington is too late to prevent a multi-billion-dollar collection of suits. Make no mistake, these companies bid on the Nortel patent package with the intention of clobbering Google with it. You would have to purchase each product individually. A trillion dollar Internet-based economy down the drain because someone patented an obvious idea. Friday, December 7, 2012. Of se...

Wednesday, December 31, 2014. Not that you asked, but some thoughts on games of 2014 and podcasts and stuff. 2014 was an absurdly tumultuous year for me. If it’s all well and good, I’d rather avoid going through the gut-wrenching uncertainty and ego-shattering sense of “oh fuck, what have I done? Should I be doing a podcast right now, there would no doubt be some kind of “best games of 2015" type list discussion thing. Right now there is no show, so instead…behold…a listicle. I ignored the campaign compl...
