Intelligent In-Vehicle Device Based on ARM-Linux Techniques

A new Intelligent Transportation System (ITS) is introduced and some ideas about instruction trigger position (ITP) are presented. The design of terminal devices based on an embedded ARM-Linux system in vehicles is presented in detail, including the design and development of both hardware and software

Correctness proofs for device drivers in embedded systems

Journal ArticleComputer systems do not exist in isolation: they must interact with the world through I/O devices. Our work, which focuses on constrained embedded systems, provides a framework for verifying device driver software at the machine code level. We created an abstract device model that can be plugged into an existing formal semantics for an instruction set architecture. We have instantiated the abstract model with a model for the serial port for a real embedded processor, and we have verified the full functional correctness of the transmit and receive functions from an open-source driver for this device

Interface Synthesis for Embedded Applications in a Codesign Environment

In embedded systems, programmable peripherals are often coupled with the main programmable processor to achieve desired functionality. Interfacing such peripherals with the processor qualifies as an important task of hardware software codesign. In this paper, three important aspects of such interfacing, namely the allocation of addresses to the devices, allocation of device drivers, and approaches to handle events and transitions have been discussed. The proposed approaches have been incorporated in a codesign system MICKEY. The paper includes a number of examples, taken from the results synthesized by MICKEY, to illustrate the ideas
