SLAC CAMAC CRATE CONTROLLER CCU2 WITH AUXILIARY CONTROLLER BUS INTERFACE

摘要

The development of a new CAMAC type U crate con¬troller, compatible with the SLAC parallel branch high¬way, is described. The controller also provides an in¬terface for the Standard Auxiliary Controller Bus, con¬trol and timing logic to implement a handshake system between the host computer and the crate controller, an internal timing generator for Dataway cycles, and a LAM handling facility with priority arbitration along the parallel branch highway. A highly integrated module implementation was achieved through extensive use of firmware and finite state logic machine realizations of many crate controller functions.
