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] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

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

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

[0035] The concrete steps of described step 1 include:

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

[0037] 2. the state inquiry module inquires about the FIFO state, and when the FIFO has data, the protocol analysis module is notified, and the source address (mainframe CPU) and destination address (embedded processor) are analyzed and the data length is analyzed;

[0038] ③The status query module inquires whether the sent data is all written, and after the writing is completed, the status query module notifies the DMA transmission module to tra...

Abstract

The invention relates to a high-performance multi-node interconnection parallel transmission control method, and its technical characteristics are as follows: step 1, host CPU sends data to TPCM module embedded CPU; step 2, host CPU sends data to TCM chip; step 3. The TCM chip sends data to the host CPU. The invention realizes the direct channel between the main board and the domestic credible encryption 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 data transmission method of a trusted platform control module, 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 embedded processor is integrated in the trusted platform control module to realize the configuration of the trusted cryptographic chip and the preprocessing function of data . Because the data in the traditional implementation method needs to be forwarded by the embedded processor, the number of data transmissions 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. Contents of the inventi...
