The development of an asynchronous data processing system is usually based on dedicated asynchronous elements. Advanced general-purpose microprocessors have a set of features facilitating designing of an asynchronous unit. The paper presents an architecture of the system implemented on Texas Instruments MSP430 micro-controllers using a principle of the(More)
The signal-driven data acquisition method for nonstationary signals, such as a level crossing sampling (LCS) [1, 2], allows data sampling at a rate significantly below the Nyquist rate. It can be achieved for the burst signals due to the following LCS advantages: no data sampling if a signal remains constant and a data sampling only at the time instants(More)
We propose an advanced signal-driven sampling method that uses the level-crossing sampling technique based on the selected signal sampling and non-uniformly distributed quantization levels. The number of the quantization levels is chosen to compress the volume of sampled data. The proposed sampling method is targeting sporadic signals. The trade between the(More)
A web-based data acquisition system is proposed as a research tool of the energy efficiency monitoring project of the test stands. Basic requirements for the architecture of the data acquisition system are discussed. The architecture of the data acquisition system is proposed to provide the real-time interface with sensors, to acquire and to log data from(More)

The presented embedded configurable interface device is a feasible solution for interfacing different types of smart sensor systems and user devices. A micro-controller with dedicated I/O interface driver and a smart sensor communication driver is necessary in creating the seamless interface between end-user and smart sensors systems.
The asynchronous data processing is a method that was already used in the computers of the first generation. For example asynchronous data processing was successful used in the first in Latvia built computer LM-3 [1]. The revival of asynchronous processing started in nineties of the past century. The key benefits of asynchronous system [2] are very low(More)
