MEMORY SYSTEM IN A DUAL PROCESSOR DEVICE AND A METHOD OF INITIALISING MEMORY IN A DUAL PROCESSOR DEVICE

摘要

A memory system in a dual processor device, in which one of the processors is a master processor (MP) and the second is a slave processor (SP). These processors have separate memory blocks, and the software of the master processor (MP) is stored in the memory block (Flash M) of the master processor (MP). By the invention, the memory block (Flash M) includes additionally data describing the differences between the software of the master processor (MP) and the software of the slave processor (SP). According to a method of initializing a memory system of a dual processor device, in the memory block (Flash M) of the master processor (MP) there are located additional data, describing differences between the software of the master processor (MP) and the software of the slave processor (SP), and during initialization of the system the starting application of the master processor (MP) is activated, the starting application of the slave processor (SP) is copied to the slave processor (SP) and next the software of the master processor (MP) is copied to the memory (RAM S1) of the slave processor (SP) from the memory (Flash M), and basing on the data, describing differences between the software of the master processor (MP) and the software of the slave processor (SP), changes are made in the content of the memory (RAM SI) of the slave processor (SP).
