Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] In the embodiment of the present invention, a master device interface and a slave device interface are added to the structure of the existing bus crossover module, and the system-level sacrificial cache memory is expanded in a loopback manner to store the latest data written by each master device. The read and write operations of the device are determined by the determination unit and the victim cache. If the determination is satisfied, the read and write operations are completed in the victim cache, which can reduce the amount of data accessed by the memory interface.
