Re: Inside story: Parallel bars (The Economist)
In a very loosely related theme, I saw an ad recently for the 2011 Hot Chips conference in San Francisco that included the title "The XMOS Architecture and the XS1 Chips".

Re: XMOSCOPE
<t>In case you haven't chosen an amplifier for your scope, there is the National LMH6518 which is a DC-coupled digitally controlled 900 Mhz amplifier. In the Applications section, its use as an oscilloscope is mentioned. <br/> <br/> I recently bought a couple of these devices for a different applica...

Re: XCommons Foundation
<t>Hi,<br/> <br/> I thought I had posted this earlier but anyway.......................<br/> <br/> Is there any interest in a simple floating point library. Some time ago I started porting the SoftFloat library (J.Hauser) to XC and assembler. I got as far as doing the conversions to and from integer...

Re: 500 MIPS event-driven RISC processor + 100% deterministic
Hi,
I found that when measuring time delays in the 10 - 100 nsec range, using fast-mode gave about 10% higher counts than when it was not invoked.

Re: XSIM problems
Hi Kris, I am running XP Pro version 5.1, SP 3 on a IBM Thinkpad 2003 vintage. I have tried all the recent XMOS versions 9.92 thru 10.4.2 all with the same results. Strangely, just once, the Waves and Signals windows did appear as tabs in the console window but only the once? This is really not any ...

Re: XSIM problems
Double clicking on the generated vcd file in the project explorer should open it in both the signals and the waves view within the c/xc perspective. This did not appear to work in any of the four recent versions of the IDE that I have on my laptop, other than opening the file as text in the editor ...

Re: XMOS for Phased Array Ultrasonic Rangefinder
Hi, I have been working on a optical rangefinder using a pulsed laser diode to measure the level in water wells. I posted an early version of the software in the projects section. Obvious problems for this approach are that wells are not always dead straight, there may be obstructions in the way, eg...

Re: XSIM problems
I have finally found out how to display waveforms in XSIM, at least on my system!!! I opened a new waveform window using Window/Open Perspective/ Waveforms, then clicked on the Load VCD file icon. This loads the Signals window, from which the ports/signals can be selected. An earlier mistake was usi...

XSIM problems
Hi, I cannot seem to get the IDE to open the Waves and Signals windows in the console screen, instead a vcd file is shown as a text file in the editor window. I have tried opening a new waveform window using "Open Perspective" and loading the UART loopback example. After opening the file,a...
