Opis:: The article presents the tests of method for real-time data acquisition from embedded systems using Matlab software. Data transmission is performed using several common use interfaces: UART/USB, Ethernet, Bluetooth and WiFi. The article includes a description of a protocol, measuring station based on two types of embedded system, implementing the proposed protocol, as well as a description of the algorithm of test programs. Experimental studies were performed using a STM32F4 microcontroller and Raspberry PI-3 single-board computer. Executed tests related: (1) the average transmission time, (2) the effective throughput of a full cycle of data exchange, (3), the required working time of Matlab to handle the transmission, and (4) the stability of the program timer used for periodic data transmission calls. Experimental studies have shown that it is possible efficient data exchange between the embedded system and Matlab while maintaining the real-time requirements.

Opis:: High-Throughput Data Acquisition Systems are an essential part in many scientific experiments, and the processing of the large amount of data, represents a challenge in designing systems capable of managing such volume of data. Owing to the nature of this type of experiments, the processes responsible for gathering the data from devices that measure real-world phenomena, and those processes in charge of distributing the data to monitoring and/or controlling systems, shall communicate with accuracy and reliability. By running those processes concurrently in a multi-processor computer system, such requirements of accuracy and reliability can be achieved. In this paper, we present the design of a C++ framework, which implements a ring-buffer by using shared-memory as a fast mechanism of data communication among processes. Likewise, the framework controls the access to data in the shared ring-buffer by implementing inter-process synchronization objects in shared-memory. The effectiveness of the proposed solution has been evaluated by evaluating the latency time from when a new data is written into the shared ring-buffer and the longest instant when such a data is gathered. After the experimental test, the results show that it is possible to develop a C++ framework for helping programmers to create data acquisition system when a high-throughput data-stream is involved, getting suitable performance by using shared-memory.
