Express Logics ThreadX® RTOS Powers ARMs New Cortex-R4 Processor
Summary
ThreadX is especially effective at using a minimal amount of memory, leaving more for the application, and helping to reduce power consumption and accompanying heat.Following the same engineering approach established with the M3 earlier this year, ARM used ThreadX extensively during the development of the Cortex-R4 and its integrated, advanced interrupt handling capabilities as part of a comprehensive validation process.ARM’s engineers were able to quickly simulate complex environments, substantially reducing test development times and enabling the company to release the Cortex-R4 processor on schedule.“As with the Cortex-M3, ThreadX enabled us to test many of the operating characteristics of the Cortex-R4 processor to ensure it would perform well in the most demanding of real-time applications,” commented Richard York, CPU product manager at ARM.ARM’s engineers were able to quickly simulate complex environments, substantially reducing test development times and enabling the company to release the Cortex-R4 processor on schedule.“As with the Cortex-M3, ThreadX enabled us to test many of the operating characteristics of the Cortex-R4 processor to ensure it would perform well in the most demanding of real-time applications,” commented Richard York, CPU product manager at ARM.
