Problems solved by technology

Some applications on the interface based on this high-speed bus may cause the performance of the entire bus system to degrade
Traditionally, the forwarding of multi-channel messages is written into FIFO through parallel input channels, and then forwarded from FIFO to multi-output channels, which limits the data transmission rate.

Embodiment

[0029] as attached figure 1 The classic 2-input 5-output channel message forwarding structure diagram is shown. In the figure, two channels in the 2-input channel obtain the control right of the serial channel according to certain rules, and write the message into the serial channel. Then the serial channel forwards the message to the corresponding output channel. This transmission method is easy to implement and less error-prone, but this method converts multiple input channels into one serial channel for forwarding messages. Therefore, as the number of input channels increases, the data transmission rate is greatly affected.

[0030] attached figure 2 This is an improved message forwarding structure diagram of 2 input channels and 5 output channels. When channel 1 and channel 2 are transmitting, they will first enter the discriminator to determine the type of message. If the messages of channel 1 and channel 2 belong to the same output channel, first write the messages in...

Abstract

The invention discloses a multi-channel message transmitting method. The multi-channel message transmitting method comprises the following steps of enabling messages to firstly enter a plurality of input channels, wherein the input channels are originating terminals of the messages and control the number of the messages; transporting the messages in the input channels to a judger and enabling the judger to judge whether the messages input by the channels are transmitted in a parallel mode or a serial mode; directly transmitting the messages of the input channels to corresponding output channels when the messages are transmitted in the parallel mode, namely, the messages are transmitted through different channels; writing the messages into serial channels and transmitting the messages to the corresponding output channels through the serial channels when the messages are transmitted in the serial mode, namely the messages are output through the same channel. Compared with the prior art, the multi-channel message transmitting method avoids the problem that the messages retain in the serial channels for a long time due to the fact that the messages belong to the same output channel are transmitted in the serial mode and is strong in practicability.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a highly practical and multi-channel message forwarding method. Background technique [0002] As the computer's data processing capability becomes stronger and stronger, the processor needs to exchange more and more data with Cache, memory, peripherals, and processors. In order to meet this demand, PCIE and QPI have emerged in recent years. and other high-speed data transmission buses. Some applications on the interface based on this high-speed bus may cause performance degradation of the entire bus system. Traditionally, the forwarding of multi-channel messages is written into FIFOs through parallel input channels, and then forwarded from FIFOs to multiple output channels, which limits the data transmission rate. [0003] Based on this, a method for multi-channel message forwarding is now proposed. By using this method, the input channel messages of multiple messages...
