Abstract:
Ein Prozessmessgerät mit einem ersten Prozessor (21), welcher in ersten Verarbeitungszyklen mit einem ersten Algorithmus eine Messwertverarbeitung durchführt; und einen zweiten Prozessor (25), welcher Koordinations und/oder Kommunikationsaufgaben wahrnimmt. Der zweite Prozessor (25) liest in Zeitabständen, die grösser sind als der erste Verarbeitungszyklus einen Kontrolldatensatz aus dem ersten Prozessor (21), und führt anhand des Kontrolldatensatzes den ersten Algorithmus aus um die korrekte Funktion des ersten Prozessors zu verifizieren.
Abstract:
Architectures and circuits are described for various implementations of a memory-centric computing system for DSP and other compute-intensive applications. A shared, reconfigurable memory system is accessible to both a host processor or controller and to one or more execution units such as a DSP execution unit. By swapping memory space between the processor and the execution unit so as to support continuous execution and I/O, improved performance is achieved while cost is reduced. The shared memory system includes multiple reconfigurable memory segments to allow allocation of various amounts of memory to respective execution units or I/O or DMA channels as needed to optimize performance. A "virtual two-port" solution is also described for using single-port memory in the shared configuration with multiple address sources.

Abstract:
Disclosed is a process measurement apparatus comprising a first processor (21) which processes measured values in a first processing cycle by means of a first algorithm, and a second processor (25) that performs coordination tasks and/or communication tasks. The second processor (25) reads a set of reference data out of the first processor (21) at intervals that are greater than the first processing cycle and executes the first algorithm based on said set of reference data in order to verify whether the first processor functions properly.
