Express Logic brings high performance to Cortex-M4

by K C Krishnadas, TechOnline India - February 02, 2012

The combination of ThreadX RTOS and NetX TCP/IP stack offers high-performance near-wire speed solution for consumer, medical, and industrial-control applications.

Express Logic, into royalty-free real-time operating systems (RTOS), has said it has ported its ThreadX RTOS and NetX TCP/IP stack to support a wide range of processors based on ARM’s Cortex-M4.

ThreadX has been deployed in over a billion electronic products in the areas of consumer electronics, medical devices, and industrial control systems — systems where Cortex-M4 is an ideal fit. NetX Duo has achieved near-wire speed on Cortex-M4-based platforms from Freescale and STMicroelectronics, the company said.

The ARM Cortex-M4 processor is the latest embedded processor by ARM  developed to address digital-signal control markets that demand an efficient, easy-to-use blend of control and signal-processing capabilities. The combination of high-efficiency signal-processing functionality with the Cortex-M family’s low power, low cost, and ease of use makes it an ideal, flexible solution for motor control, automotive, power management, embedded audio and industrial automation markets.

“ARM’s Cortex-M4 processor brings floating point and DSP to the already powerful M3, which is extremely popular among our customers,” commented William E. Lamie, President, Express Logic.

Express Logic’s ThreadX RTOS is a small, fast, royalty-free RTOS that provides priority-based preemptive scheduling, optimized context switching, and an intuitive, easy-to-use API. NetX Duo is Express Logic’s high-performance dual IPV4/IPv6 TCP/IP stack, that has been shown to deliver near-wire speed on Cortex-M4 platforms, including Freescale’s Kinetis K40/K60 and STMicroelectronics’ STM32F407. In addition, ThreadX supports all other announced Cortex-M4-based processors, including Atmel’s AT91SAM4S and NXP’s LPC43xx.
