Problems solved by technology

However, in the high-performance embedded field, the operating systems used are all real-time operating systems, which do not support the two methods of pipes and Unix Sockets, and if the AMP architecture is adopted, that is, the operating system is deployed to the core, for multiple If the core CPU is not specially designed, not every core has an IP. Generally, only core 0 has an IP, and other cores load the system through core 0.
At this time, if TCF is used to manage the system, the TCF agent can only be deployed to core 0, and the information of other cores needs to be collected by core 0. In this way, a task of collecting information must be implemented in other cores, and core 0 There must be a task that can receive information from other cores, which invisibly increases a lot of workload

Embodiment 1

[0029] This embodiment provides a TCF communication method based on EIPC, including the following steps:

[0030] Step A: Initialize send and receive handles:

[0031] The TCF client and the TCF agent call the msgOpen function of EIPC to generate sending and receiving handles respectively;

[0032] Step B: The TCF agent enters the accept state, and the TCF client enters the connect state:

[0033] After step A is completed, the TCF agent sends an asynchronous request event IPCAsyncReqAccept. Next, the TCF agent will create a thread to respond to this event. Considering that there is no accept function similar to network programming in the interface function of EIPC, but EIPC receives The function can be blocked, therefore, the TCF agent uses the blocking function of the receiving function to realize the accept function. Similarly, the TCF client will send an asynchronous request event IPCAsyncReqConnect, and the TCF client will also create a thread to respond to this event. ...

Embodiment 2

[0046] This embodiment provides a TCF communication device based on EIPC, including an upper computer terminal and a lower computer terminal, wherein, the upper computer terminal runs a TCF client, and the lower computer terminal is provided with multiple CPUs, and each CPU is equipped with multiple Each core runs a TCF agent, and an EIPC communication channel is set between any TCF client and any TCF agent.

Abstract

The present invention provides a kind of TCF communication method based on EIPC, comprises the following steps: Step A. Initialize send and receive handle; Step B. TCF agent end enters accept state, TCF client enters connect state; Step C. Initialize EIPC communication channel . At the same time, an EIPC-based TCF communication device is provided. The present invention can realize message communication and bulk data transmission between multi-processors and multi-tasks only by using a small number of functions, and has the characteristics of reliability, priority-based, real-time embedding; unified interface and convenient setting; It can not only realize the inter-core communication in the same CPU, but also realize the inter-core communication of different CPUs, and effectively complete the interconnection between the processors; it can deploy the TCF agent to all cores of the CPU; Monitor through the TCF agent.

Description

technical field [0001] The present invention relates to communication protocols in the technical field of computer software, in particular to an EIPC-based TCF communication method and equipment. Background technique [0002] In the field of national defense, there are a class of computing-intensive applications, such as information intelligence, radar signal processing, and electronic warfare. In order to respond to complex battlefield situations and respond quickly, these applications require a high-performance, high-reliability, Highly stable computers to help them analyze and process data. Moreover, with the continuous development of information technology, the future battlefield is no longer a confrontation between a single equipment and a single arm. In order to win a local war under a high degree of informationization, it is necessary to coordinate various equipment and arms to make unified decisions. As a result, the national defense field has ushered in the era of ...
