Description:

The majority of the industrial systems are implemented based on data acquisition systems. Since this outside world is analog, the demand for real time, reliable, safe, secure, high resolution and faster acquisition systems has been growing.
In this dissertation, it is intended to develop a generic real time acquisition system that tackles this requirements, based on Linux, in which some tasks can be offloadedD through dedicated hardware in the FPGA, in order to satisfy the real time requirements of the system. The proposed system is modulated as an embedded system based on the SO Linux, which it is able to acquire the signal from the outside world in the proper format, granting accuracy and precision to the obtained data, and it is able to be used in the monitor and control of the industrial processes

Objectives:

The development of this project encompasses five main objectives: Design Space Exploration, Acquisition Board, Hardware Abstraction Layer, Accelerated HW/SW Subsystem and Assembler Demonstrator.
The first goal consists, mainly, in a development requirements bring up, where the author is responsible for researching and analyzing the information relevant to the development of the project, and preparing all the software and hardware tools.
The following goal is to design and build a PCB that comprises the acquisition and conditioning of the signals from the outside world.
Afterwards, the goal is to develop a hardware abstraction layer that hides all the details of the implementation of the peripherals.
The fourth goal is to accelerate the acquisition subsystem by RT-patching the SO Linux and applying shared memory mechanisms. Finally, the last goal is to mount integrally the system and to test it thoroughly, collecting all the relevant results.
