Abstract

A CAMAC crate controller is developed where three T425-25S 32-bit transputers are installed. The crate controller (CC) conforms to the specifications of the EUR 6500e CAMAC standard. It can be used as a stand-alone CC and also as an auxiliary crate controller (ACC). The transputers on the CC are enabled to execute CAMAC dataway operations independently under the supervision of an arbitration logic. Each transputer is provided with an independent register set. Owing to the transputer, the CC´s can be easily networked through the connection of serial links. The CC´s in the network make accesses to front-end CAMAC modules in the individual crates in parallel, communicating with each other. Data are read from front-end CAMAC modules, stored into large memory, processed and then submitted to the network concurrently and autonomously
