The present invention relates to a method for transferring data between at least two processors (11, 12). In this method, the processors communicate with each other by means of a common memory area such as a register, at least one of the processors writing to said memory area and at least one of the processors reading from said memory area. In order to avoid the transmission of erroneous data between the processors in the simplest possible manner, (a) an interruption signal is applied to the interruption input (INT_IN) of each reading or writing processor (11, 12), the mutual order in time domain of the interruptions produced by all interruption signals being constantly kept the same, and the interval between them being also kept within predetermined limits, and (b) the significant moments of read and write operations (RD/WR) of different processors are determined at predetermined points in time domain with respect to the interruption moments of said interruption signals, a read operation performed by each processor being separate in time domain from the write operations performed by the other processors and a write operation performed by each processor being separate in time domain from the read and write operations performed by the other processors. |
