	Over the last years the mobile and hand-held device market has seen a dramatic performance improvement of the microprocessors employed for these systems. As an interesting side effect, this brings the opportunity of adopting these microprocessors to build small low-cost embedded boards, featuring lots of processing power and input/output capabilities. Moreover, being capable of running a full featured operating system such as GNU/Linux, and even a control system toolkit such as Tango, these boards can also be used in control systems as front-end or embedded computers. In order to evaluate the feasibility of this idea, an activity has started at ELETTRA to select, evaluate and validate a commercial embedded device able to guarantee production grade reliability, competitive costs and an open source platform. The preliminary results of this work are presented.

	This paper presents current status and upgrade plan of a data-acquisition (DAQ) system for SACLA user experiments. The X-ray Free-Electron Laser facility in SPring-8, SACLA, has achieved first SASE lasing in June 2011, and has delivered X-ray laser beams to users from March 2012 [1]. For the user experiments at SACLA, a dedicated DAQ system has been developed. The DAQ system is currently capable to operate with maximum 10 sensors of multiport Charge-Coupled Device (MPCCD) for X-ray detection. With this configuration, the MPCCD generates 10 MBytes data per accelerator beam shot, which is equivalent to 5 Gbps data rate at 60 Hz beam repetition. During the first experimental period from March to July 2012, the DAQ system carried out 25 experimental proposals that covered atom, molecular and optical physics, ultrafast science, material science, and structure biology. In this paper, we present an overview of the DAQ system with special emphasis on the high-speed data cache, and data visualization by on-site PC clusters. An upgrade plan of the DAQ storage more than 3 PBytes and the on-line data-analysis with the off-site 10 PFlops supercomputer ("K computer") are also discussed. [1] T.
