By implementing a microprocessor-based CAMAC module capable of being programmed to function as a time plot or a timed reading controller, the capabilities of the experimental area serial CAMAC control and data acquisition system at Fermilab have been extensively increased. These modules provide real-time data gathering and pre-processing functions synchronized to the main accelerator cycle clock while adding only a minimal amount to the host computer's CPU time and memory requirements. Critical data requiring a fast system response can be read by the host computer immediately following the request for this data. The vast majority of data, being non-critical, can be read via a block transfer during a non-busy time in the main accelerator cycle. Each of Fermilab's experimental areas, Meson, Neutrino and Proton, are controlled primarily by a Lockheed MAC-16 computer. Each of these three minicomputers is linked to a larger Digital Equipment Corporation PDP-11/50 computer. The PDP-11 computers are used primarily for data analysis and reduction. Presently two PDP-11's are linked to the three MAC-16 computers.
