Simultaneously read HSCMRRN060MDSA3 honeywell pressure sensor digital SPI output

Hello! I am new to Arduino, but very excited about the possibility that this microprocessor can give to my field of research. I work with as a university researcher in the wind turbine field, for my experiment I need to read simultaneously the data coming from 7 HSCMRRN060MDSA3 honeywell pressure sensor, http://sensing.honeywell.com/product%20page?pr_id=141717 , they have a digital SPI output. I've read here http://forum.arduino.cc/index.php?topic=157940.0 and here http://arduino.cc/en/Reference/PortManipulation that it is possible to read 8 inputs in one instruction cycle, anybody knows a way to connect the SPI output sensor to the microprocessor to do so? Could you give me an estimate of the time to read all the 8 input with an Arduino Yun? Thanks a lot, Andrea
