AI Technical Summary

Technical Problem

In the existing technology, the debugging module cannot effectively access the tightly coupled components of the CPU, resulting in poor coverage of real-time data during software program operation and affecting the debugging function of the debugging module.

Method used

The debug module is configured as the master device of the processor's internal bus, connected to the processor's internal bus via the SBA interface. It prioritizes access requests from the processor core and handles concurrent access requests through arbitration logic, ensuring that the debug module can access multiple tightly coupled components.

Benefits of technology

The debugging module has improved its coverage of real-time data during software program execution, enhanced its debugging capabilities, and can accurately locate errors in multiple tightly coupled components.

Abstract

The application discloses a processor, a control method of the processor and an electronic device, and belongs to the technical field of computers. The processor provided by the application comprises a processor core, a debugging module, a processor internal bus, and a plurality of tightly coupled components. The debugging module is connected to the processor internal bus through a system bus access (SBA) interface. The processor core and the debugging module both serve as master devices of the processor internal bus, and the plurality of tightly coupled components are all connected to the processor internal bus and serve as slave devices of the processor internal bus. By taking the debugging module as a master device on the processor internal bus, the application provides the access capability of the debugging module to the plurality of tightly coupled components, and is beneficial to improving the debugging capability of the debugging module.
