SPECS : A serial protocol for experiment control system in LHCb

Abstract : This document describes the SPECS protocol and its implementation. The SPECS is a 10 Mbit/s serial bus, designed to be simple, cheap, reliable and to work in radiation sensitive environments. It is mainly used to download and read back the configuration of the electronics located on the detector. It is made of Master PCI boards and slave daughter boards, provides I2C, JTAG and parallel interfaces for the users, and is delivered with a software patch.
