This project consist aims at improving the current process of data acquisition of an instrumented PIG. The current system has a jitter which reduces the maximum acquisition capability. This reduction decreases the efficiency of the characterization of oil and gas pipelines. In order to minimize the jitter, we use Fast Interrupt Request on demand for acquisition. In this work, we present a study that focuses on ARM interrupts, emphasizing the Fast Interrupt (FIQ) and its different features in comparison to commons interrupts. Furthermore, we then conducted a comparative analysis of the jitter for these interrupts. Afterwards, we approached the creation of a SPI-DMA interface that needed to be developed to satisfy the FIQ restrictions. Associated with these restrictions, we discussed the Linux Kernel code and configuration changes that were necessary for the FIQ operation. Finally, we dealt with adaptations in the current system architecture.
