Problems solved by technology

Because the data in the traditional implementation method needs to be forwarded by the embedded processor, the number of data transfers is virtually increased, and the efficiency is low. The performance of the transmission channel directly affects the performance of the entire system and the user's experience.

Embodiment Construction

[0032] The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings:

[0033] A high-performance multi-node interconnection parallel transmission control method, such as figure 1 with figure 2 As shown, including the following steps:

[0034] Step 1. The host CPU sends data to the embedded CPU of the TPCM module;

[0035] The specific steps of step 1 include:

[0036] ①The host CPU encapsulates the data according to the data encapsulation protocol and sends it to the FIFO;

[0037] ②The status query module queries the FIFO status, and when there is data in the FIFO, it notifies the protocol analysis module to analyze the source address (host CPU) and destination address (embedded processor) and analyze the data length;

[0038] ③The status query module queries whether all the sent data is written. After the writing is completed, the status query module informs the DMA transmission module to transfer the data from the dat...

Abstract

The invention relates to a high-performance multi-node interconnected parallel transmission control method, which is characterized in that the method comprises the following steps: step 1, a host CPUsends data to an embedded CPU of a TPCM module; step 2, that host CPU send data to the TCM chip; 3, that TCM chip send data to the host CPU. The invention realizes the direct channel between the mainboard and the domestic trusted cipher chip, simplifies the data transmission link and improves the performance of the system.

Description

Technical field [0001] The invention belongs to the technical field of trusted platform control modules, and relates to a trusted platform control module data transmission method, in particular to a high-performance multi-node interconnection parallel transmission control method. Background technique [0002] The traditional trusted platform control module (TPCM) uses a dedicated trusted cryptographic chip (TCM) to realize the trusted algorithm function, and the trusted platform control module integrates an embedded processor to realize the configuration of the trusted cryptographic chip and the preprocessing of data . Since the data in the traditional implementation method needs to be forwarded through the embedded processor, the number of data transfers is virtually increased, and the efficiency is low. The performance of the transmission channel directly affects the performance of the entire system and the user experience. Summary of the invention [0003] The purpose of the p...
