AbstractAbstract
[en] Many labs try to boost existing data acquisition systems by inserting high performance intelligent devices in the important nodes of the system's structure. This strategy finds its limits in the system's architecture. The CHADAC project proposes a simple and efficient solution to this problem, using a multiprocessor modular architecture. CHADAC main features are: a) Parallel acquisition of data: CHADAC is fast; it dedicates one processor per branch; each processor can read and store one 16 bit word in 800 ns. b) Original structure: each processor can work in its own private memory, in its own shared memory (double access) and in the shared memory of any other processor (this feature being particulary useful to avoid wasteful data transfers). Simple and fast communications between processors are also provided by local DMA'S. c) Flexibility: each processor is autonomous and may be used as an independent acquisition system for a branch, by connecting local peripherals to it. Adjunction of fast trigger logic is possible. By its architecture and performances, CHADAC is designed to provide a good support for local intelligent devices and transfer operators developped elsewhere, providing a way to implement systems well fitted to various types of data acquisition.

AbstractAbstract
[en] The CAMAC crate autonomous controller JCAM-10 is designed around an INTEL 8080 microprocessor in association with a RAM and REPROM memory. The concept of the module is described. Data transfers between CAMAC modules and the memory are optimised. In fact, the JCAM-10 is a microcomputer with a set of 1000 peripheral units represented by the CAMAC modules commercially available

AbstractAbstract
[en] The dosimetry laboratory of NRCN employs a 2271 Harshaw automatic TLD card reader. The system logic performs only basic parity checks of the data which is sent to the peripheral equipment, besides the upper and lower dose limit alarms. Other errors may remain undetected until the data analysis stage. A pc computer was connected to the automatic card reader system. The pc computer controls the operation of the system while receiving, checking and recording the data on a magnetic media. A serial number is given to each record and other specifications as date, unit and type of analysis are also added to the data file. (author)

AbstractAbstract
[en] A data acquisition and control system for the ETA-BETA experiment is presently under development at the C.G.I. of Padua. The system is based on a local minicomputer TI 960A linked via a telephone line to a host computer (IBM 370/158). The data collected during the experimentation are initially stored on a local disk unit and then transferred into large permanent files of the host computer. The experimentation requires a strict interaction between the operator and the computer. This interaction requires a sequence of operations which change according to the experiment requirements in an unpredictable manner. To avoid a continuous reprogramming of the operation sequence, to achieve a smooth and automated experimentation, a command interpreter which acts as an interface between the software modules performing different tasks and the operator has been implemented. The interpreter reacts to a command by activating a program which, under the operating system supervision, runs as an independent task or as a subroutine dynamically loaded in core. The operating power of the interpreter is enhanced by structure commands which perform looping and conditional branching as in a procedural programming language. The interpreter is open ended in the sense that new commands can be added during the operation and sequences of commands can be grouped in a procedure which can be executed by a single procedure call command. Nesting of structure commands and procedures is virtually unlimited
