Abstract
A method and a data bus subscriber are described for processing process data in a local bus, in particular a ring bus, the method including receiving a first symbol during a first number of working cycles, with the first symbol comprising first process data; loading at least one first instruction from an instruction list during the first number of working cycles, receiving a second symbol during a second number of working cycles, with the second symbol comprising second process data, processing the first process data contained in the first symbol with the at least one loaded first instruction during the second number of working cycles, and loading at least one second instruction for processing the second process data of the second symbol during the second number of working cycles.
Claims19
A method for processing data at a data bus subscriber in a local bus the method comprising:
- receiving a first symbol during a first number of working cycles, wherein the first symbol comprises first process data;
- loading at least a first instruction from an instruction list during the first number of working cycles;
- receiving a second symbol during a second number of working cycles, wherein the second symbol comprises second process data;
- processing the first process data contained in the first symbol with the at least one loaded first instruction during the second number of working cycles;
- and
- loading at least one second instruction for processing the second process data from the second symbol during the second number of working cycles,
- wherein the first number of working cycles and the second number of working cycles do not overlap.
A data bus subscriber of a local bus, comprising:
- a bus receiver to receive symbols via the local bus, the bus receiver receives the symbols in a respectively predetermined number of working cycles;
- an instruction loader that accesses processing instructions from a memory;
- and
- a processor to process a process data from the received symbols based on the instructions loaded from the memory of the processor,
- wherein the loader is adapted to load to the processor at least one instruction for processing first process data of a first symbol during a first number of working cycles in which the first symbol to be processed with the instruction is received, and
- wherein the processor is adapted to process the first process data received in the first symbol using the loaded at least one instruction within a second number of working cycles in which a second symbol is received,
- wherein the first number of working cycles and the second number of working cycles do not overlap in time.
