The objective of this work is to provide a low cost high resolution fuel indicating of the vehicle. Another object of the present invention is to provide a system that tracks the fuel filled at filling station. The challenges addressed in the propose work are calibration of non linear fuel tank to fetch the present fuel information, design of the signal processing circuit to convert fuel level information from the non linear tank to fuel in litres and device a smart computing system for the calibration of filled fuel.
相似文献All modern computational devices consist of ALU. With increase in complexity of software and the consistent shift of software towards parallelism, high speed processors with hardware support for time consuming operations such as multiplication would benefit. Smaller, compact devices such as IoT devices need to run software such as security software and be able to offload computation cost from the cloud. In this paper, a high speed 8-bit ALU using 18 nm FinFET technology is proposed. The arithmetic and logical unit consists of fast compute units such as Kogge Stone fast adder and Dadda multiplier along with basic logic gates. In this paper, an ALU with each compute unit optimized for speed is proposed, while responsibly consuming area. Dadda multiplier is of 8 × 8 architecture as opposed to conventional approach of 4 × 4 making it a true 8-bit ALU. Simulation and analysis is done using Cadence Virtuoso in Analog Design Environment. The transistor count of proposed design is 5298, the power consumption is 219 µW and maximum delay is 166.8 ps. The design is also expected to consume a maximum of one clock cycle for any computation.
