Bus protocol-independent communication method for scalable processor architecture version 8 (SPARC V8) monitoring software

Abstract

The invention discloses a bus protocol-independent communication method, which is used for establishing a command-driven communication protocol independent of a specific communication port between a host and a target machine. The host comprises a file management and data transmission module, a protocol command processing module and various bus communication processing modules. The target machine comprises a command execution and data transmission module, a command resolution module and the various bus communication processing modules. The method is characterized in that: the host further comprises a communication management module arranged between the protocol command processing module and the various bus communication processing modules; the target machine further comprises the communication management module arranged between the command resolution module and the various bus communication processing modules; and the communication management module is provided with four buffer zones which are a command execution buffer zone, a command receiving buffer zone, a data execution buffer zone and a data receiving buffer zone, and manages the specific communication port.

Description

Technical field [0001] The present invention relates to a communication method independent of the bus protocol, in particular to a communication method independent of the bus protocol between a target computer using a SPARC V8 processor and a host computer using a PC. Background technique [0002] For embedded system development, monitoring software plays an important role in the debugging and application process of embedded systems. The general operating mode of monitoring software is to run a console on the host computer, run an agent software on the target computer, and transmit information or data to the target through the command parsing module. The information exchange between the agent and the console requires a communication bus. According to different types of buses, the communication protocol is also different. Therefore, the data exchange and command exchange completed in the information exchange process need to develop different information exchanges according to the ...

AI Technical Summary

Problems solved by technology

There are many kinds of communication buses between the target machine and the host machine with SPARC V8 as the processor. Therefore, the communication protocol between the target machine and the host machine involved in the monitoring software must adapt to the communication requirements of various buses. The one-to-one bus communication mode limits the wide adaptability of embedded system development
