Abstract
A parallel-processing program for system-diagnostic purposes was developed for a transputer-based readout system of a silicon vertex detector (SVD). T he data-acquisition (DAQ) system for SVD was constructed as a part of resea rch and development work for the BELLE [name of a detector for an asymmetri c collider experiment at High Energy Accelerator Research Organization (KEK )] experiment consisting of data scanners (DS), slave memory modules (SMM) and direct memory access master modules (DMM). The DS, SMM and DMM have a t ransputer as a core processor. Each transputer was linked by a point-to-poi nt connection with transputer serial interfaces (Inmos-link). The DAQ syste m was equipped with a transputer network system with the Inmos-links. The d iagnostic program has the capability to detect malfunctioning readout compo nents. To minimize the processing time during an experiment, the program ru ns in parallel on each transputer. For this purpose, the program was writte n using the programming language, occam. With the benefits of its distribut ed system architecture and without the need for any operating system, the p rogram is compact with high modularity. In this paper, we report the system architecture of this diagnostic program.
