A large memory, high transfer rate VME data acquisition system for the JET correlation reflectometer

Abstract: The current paper presents a large memory giving special emphasis to the architecture and suitability of the Linux OS for this type of applications. The system will be used on the joint european torus new correlation reflectometers composed by four microwave channels with four analogue signals each. All sixteen signals will be acquired by 12-bit VME fast acquisition channels at 2 Msamples/s achieving a total data rate of 60MB/s. Slower VME acquisition channels, with 16-bit resolution and sampling rates up to 2… Show more

“…It has been verified that it is possible to increase the capacity of data processing of PXI platforms typically used in fusion experiments [7] in a significant way. In this solution, the SCPU performs, in real time, the control of the data acquisition, the pre-processing of these data (binary to floating point conversion) and its movement to the different PCPUs These PCPUs process the data using LabView applications.…”

“…En la Figura 1.29 (extraída de [Cruz02]) se muestra un ejemplo de arquitectura similar, basada en este caso en bus VME, desarrollada específicamente para un diagnóstico del JET, que permite implementar un procesado específico sobre los datos que se están adquiriendo utilizando un único procesador digital de señal TMS320C31.…”

“…En los dispositivos de pulso largo el análisis de los datos debe realizarse de forma basada en PCI de procesado paralelo desarrollada para ISTTOK y formada por cuatro DSPs (TMS320C44) sincronizados. Otra arquitectura similar pero en este caso para VME es la que se describe en [Cruz02] y que permite aplicar un procesado específico con un único procesador digital de señal TMS320C31 sobre los datos procedentes de un diagnóstico en JET. Otro de los grandes esfuerzos en investigación que han realizado los laboratorios se ha centrado en incorporar sistemas con capacidad de procesamiento en tiempo real y especialmente con ciertas dificultades en aquellos dispositivos diseñados para experimentar en pulso largo.…”
