RTOS drives into industrial Ethernet
Unique API features a driver interface that allows Ethernet packet buffers to be directly managed within the real-time application's memory space.
TenAsys Corp has added a high performance Ethernet (HPE) driver interface to version 3.1 of its INtime real-time operating system This unique API features a driver interface that allows Ethernet packet buffers to be directly managed within the real-time application's memory space

The newest release of INtime will be demonstrated on both the Intel and Microsoft booths at Embedded World in Nuremberg, Germany.
By using the HPE interface, developers are able to bypass the TCP/IP stack and tailor the number, size, type, and scheduled delivery times of Ethernet packets to meet their specific application needs.
Ethernet packets are accessed directly via a simple hardware-independent API.
The new HPE interface eliminates packet copy operations; substantially reducing the latencies normally associated with Ethernet transfers.
Determinism of packet transmission and reception is extremely important where real-time Ethernet applications are concerned.
"The HPE interface is a boon for industrial PCs, which almost universally include one or more standard Ethernet interfaces", says Kim Hartman, TenAsys VP of Marketing and Sales.
"It enables a new level of performance for users of popular industrial software such as soft PLCs".
The HPE interface gives real-time application developers the means to control the exact time of packet transmission, using standard inexpensive Ethernet controllers.
This is ideal for building Ethernet fieldbus masters for EtherCAT, Profinet, and other real-time networks.
Many industrial Ethernet systems require masters with timing precision measured in microseconds in order to implement high-speed control loops.
Before HPE this was only possible using expensive dedicated I/O cards.
The addition of the HPE interface to the INtime RTOS makes Ethernet an even better alternative to nonEthernet fieldbus solutions.
