Module eases prototyping of time-triggered systems

LONDON — TTTech (Vienna, Austria), the time-triggered systems developer, has released TTP-IP Module which provides a high-performance node for the Time-Triggered Protocol (TTP) and is compatible with the IndustryPack standard.

The module is suitable for applications in the control of aircraft and railway systems, off-road and on-road vehicles and industrial control equipment. It will provide for rapid prototyping, as well as hardware-in-the-loop (HIL) simulation of distributed hard real-time systems.

TTP-IP Module uses the qualified TTP communication controller AS8202NF from Austriamicrosystems which supports on both channels communication speeds of 5Mbit/s with MFM or Manchester coding, as well as a communication speed of 25Mbit/s using an MII interface.

The module supports various interfaces such as RS232, RS485, analog inputs and digital inputs and outputs that are mapped to the carrier board through the I/O interface. TTP-IP Module is used with IP carrier cards for Standard PCI or Compact PCI systems. The exchangeable physical layer provides the flexibility to adapt the module to customer-specific requirements.

Freescale's MPC555 PowerPC is used as host CPU and its on-chip floating point unit allows TTP-IP Module to beused as a simulator that can run automatically generated code from tools like Real-Time Workshop Embedded Coder from The MathWorks. A 128-Kbyte dual ported RAM connects the host CPU with the IP logic interface. Both the CPU and the IP logic interface can read from and write to this memory. Simultaneous 8-bit and 16-bit accesses are possible.

To speed application development, TTP-IP Module works with TTP-Tools, TTTech's integrated software development environment for TTP-based systems. TTP-IP Module supports TTP-OS, the fault-tolerant real-time operating system that is based on OSEKtime, and is specifically designed for applications that use time-triggered technology.
