Abstract

The invention discloses a master-slave device interconnection system, a master-slave device access request processing method and a computer readable storage medium, the master-slave device interconnection system comprises an APB master device, an APB slave device, a multiplexer and arbiters; the plurality of APB main devices are connected with the input ends of the multiplexer in a one-to-one correspondence manner; the plurality of APB slave devices are connected with the output ends of the arbiters in a one-to-one correspondence manner; and each output end of each multiplexer is connected with the input end of one arbiter. According to the master-slave device interconnection system, different APB master devices can access different APB slave devices at the same time; the idle time of theAPB master device and the APB slave devices can be reduced, the APB master devices and the APB slave devices can be accessed and responded at the same time, and the access efficiency among the devicesin the same system can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular to a master-slave device interconnection system, a master-slave device access request processing method, and a computer-readable storage medium. Background technique [0002] In an APB (Advanced Peripheral Bus, peripheral bus) bus system, one APB master device will be difficult to meet user needs. To solve this problem, it is proposed to set multiple APB master devices, such as multi-core processors, in an APB bus system. [0003] At present, for the APB master device to access the APB slave device, at the same time, there is often only one APB master device accessing one APB slave device, which causes other APB master devices and APB slave devices in the system to be in an idle state and cannot support multiple pairs. There are many visits, and there is a waste of resources. [0004] To sum up, how to effectively improve access efficiency between multip...
