This video is a great demonstration by students at the University of Denver (I believe) of XMOS real-time ability using an XC1 development kit. This test is running 8 independent tasks: GPS task, ultra-sonic task, compass task, wifi receive task, wifi transmit task, pwm output task, behaviour task, and a status led task.
You must play these videos! They are very cool.
David May, and Ali Dixon discuss the origins of XMOS and how the company came into being. Starting off as a spin out from a university project at the University Of Bristol, XMOS has grown and progressed considerably over the past couple of years into what it is today. Watch the video to learn more.
Our second video based around the XMP-64 shows how Jamie Hanlon, a student undertaking a research project at University has developed programs to help him write test software to explore chip to chip communication.
Key points covered include chip latency, barrier synchronisations, and an example program to show how easy it is to program in a parallel nature utilising as many processors/cores as you need using XMOS and the XC programming language.
The XMP-64 consists of 16 quad core G-series XMOS chips (64 processors in total) arranged in a hypercube allowing for very fast communication of data between processors (1.6 billion bits per second can flow between hypercube edges).
The XMP-64 can therefore execute 25 billion instructions per second. To find out more, please watch the video. Discuss it with us in our forum!
April's project of the month on XCore goes to berni for his amazing WAV Audio Player.
An overview of the project as described by berni is as follows:
"So here is a small project that plays *.WAV files from a FAT16 formated SD card.Audio output is done using PWM and a RC filter to smooth it out.Its built very modular so you can take the hardware drivers out very easily as they are grouped in folders.
Supported wav formats:
PCM 8bit mono
PCM 8bit stereo
PCM 16bit mono
PCM 16bit stereo
Supported sample rates:
1-192Khz (nonstandard rates are ok)."
Congratulations once again to berni who will receive a XK-1 development kit for this great project!
Looking towards May, please submit your nominations to the main POTM thread here (please ensure criteria are met detailed in this post if you wish to be considered).
