  PLATO has been selected and adopted by ESA as the third medium-class Mission
(M3) of the Cosmic Vision Program, to be launched in 2026 with a Soyuz-Fregat
rocket from the French Guiana. Its Payload is based on a suite of 26 telescopes
and cameras in order to discover and characterise, thanks to ultra-high
accurate photometry and the transits method, new exoplanets down to the range
of Earth analogues. Each camera is composed of 4 CCDs working in full frame or
frame-transfer mode. 24 cameras out of 26 host 4510 by 4510 pixels CCDs,
operated in full-frame mode with a pixel depth of 16 bits and a cadence of 25
s. Given the huge data volume to be managed, the PLATO Payload relies on an
efficient Data Processing System (DPS) whose Units perform images windowing,
cropping and compression. Each camera and DPS Unit is connected to a fast
SpaceWire network running at 100 MHz and interfaced to the satellite On-Board
Computer by means of an Instrument Control Unit (ICU), performing data
collection and compression.
