In this paper, a cache coherence scheme in multi-processor is introduced. There is a specific model in each kind of software, cache coherence can be solved in AHB bus by these models. First, we use dynamic address mapping policy to realize data cache. Second, according to the randomness of application environment that set up shared cache adaptive configuration and management mechanism in the finite state machine timing sequence model of each kind of software, to ensure the system reliability. In order to support multi-tasking and multi-user operator system - Linux, the multi-processor must use shared memory technology, so this paper also introduced the memory management unit, and base on these, it focuses on how multi-processor and the AHB bus cooperate to ensure cache coherence of the whole system. We can use software execution model and hardware design to achieve instruction or data coherence between each cache and main memory. ? 2014 IEEE.
