Knowledge Centre

Welcome to our knowledge centre. In here you will find a collection of materials that we have put together to assist other embedded developers.

Whitepapers

Our whitepaper: A Comparison of Linux Alternatives for Hard Real-Time is now available. This whitepaper describes the results of our measurement of latencies for Linux 2.4, Linux 2.6, Linux 2.4 with RTAI and Linux 2.4 with LXRT on an x86-based target. The paper describes the techniques used to measure latencies and includes the results of our findings.

The paper has been updated to include the most recent results using LXRT for hard real-time. Click here to download the updated copy of our whitepaper in pdf format. If you have any feedback that you wish to provide, please send us an email at .

Developer Support

Our report: GnuArm Tool Chain Set-Up Guide is now available for download. It describes how to set up an open source tool chain for the ARM 7 and ARM 9 on a Linux PC. The document also includes information and links to code for 6 sample LED flashing projects which include:

1. A project running from FLASH for the Olimex LPC-P2148
2. A project running from RAM for the Olimex LPC-P2148
3. A interrupt driven project running from FLASH for the Olimex LPC-P2148
4. A project running from FLASH for the Keil MCB-STR9
5. A project running from internal SRAM for the Phytec LPC3180
6. A project running from external SDRAM for the Phytec LPC3180
