In this paper, an efficient remote code execution technique is proposed to implement a storage-less sensor in the internet-of-Things (IoT) paradigm. A statically installed sensor such as an environmental activity monitor includes statically compiled embedded software and only offers its pre-defined functionality. To realize a flexible code update mechanism(More)
Applications and networking are the key functions for connected vehicle. And applications of In-Vehicle Infotainment (IVI) system are one of the important characteristics in the automotive industry. Because of the fast evolution of electronic technologies, automotive industry cannot adopt new technology easily. IVI platform standard was developed by(More)
Designing a mixed-signal integrated hardware requires the mixed simulation for legacy digital blocks and analog circuits, which are usually represented by the Verilog description language for digital blocks and the SPICE circuit netlist of analog circuits. Without model translations or source-level modifications and to simulate mixed legacy Verilog models(More)
Pulse-based charging method for battery cells has been recognized as a fast and efficient way to overcome the shortcoming of slow charging time in distributed battery cells. The pulse frequency for controlling the battery charge will change within a certain range. The optimal frequency is determined to achieve the minimized battery impedance. The adaptation(More)

A secure microcontroller architecture has been proposed to protect the chip-level intrusion by injecting invalid firmware. The safe execution of the embedded firmware in microcontrollers is becoming important for applications requiring safety-critical operations, such as a safety-critical automotive controller, human-interactive interface. The chip-level(More)
This paper proposes a cloud-connected code executable architecture and its on-chip virtual instruction memory controller for the Internet of things (IoT). A remotely installed sensor system such as an environmental activity monitor commonly has an embedded processor including statically compiled embedded software in on-chip flash memory, only providing(More)
