Abstract

Upgrading the infrastructure of old scientific instruments requires the development of new hardware and software which may be expensive (in general, these projects lack of enough resources to acquire fast and modern infrastructure to become competitive and functional in the era of digital data). Particularly, the development of software for data acquisition in real time is one of the most important topics in experimental science and industry. However, the constant improvements on the data acquisition hardware, dis- courages the development of software highly optimized in order to minimize the consumption of resources like processor time and read/write memory, etc. In this work, we present a Open Source code called “X Interface to RIS” (Xitris). This is a modular and dis- tributed code which, using relatively slow processors and low memory hardware, is able to acquire, display, compress and publish (via Internet) digital data in real time. Xitris was developed for the Solar Radio Interferometer (RIS) at Geophysics Institute of the National University of Mexico (UNAM) but nowadays is working in another 3 radio observatories.
