Embodiment Construction

[0040] The method for realizing data transmission between multiprocessors described in the present invention comprises the following steps:

[0041] Step 110, initialize the port information of the Ethernet interface or the RapidIO interface of each processor. Including determining the DeviceID (device address) of the RapidIO of the sender processor, the DeviceID (device address) of the RapidIO of the intermediate forwarding processor and the MAC (Media Access Control, Media Access Control) address of the Ethernet, and the Ethernet address of the receiver processor MAC address. At the same time, the forwarding buffer space is allocated in the forwarding processor, and the read-write pointer of the initializing forwarding buffer is zero, and the Ethernet sending buffer descriptor linked list of the forwarding processor and the receiver's Ethernet receiving buffer descriptor are initialized.

[0042] Wherein, the processor includes a microprocessor, a digital signal processor (...

Abstract

The present invention relates to a method of transmitting data from the quick input and output ports to the Ethernet port. A sender processor and a forwarding processor are connected through a quick input and output interface, and the forwarding processor and a receiver processor are connected through an Ethernet interface. The present invention comprises: step 110, the sender processor, the forwarding processor and the receiver processor are initialized; step 120, the sender processor forms the to-be-sent data group into a data packet with Ethernet frame format, and writes into the forwarding buffer area of the forwarding processor; step 130, the forwarding processor makes a data sending pointer point at the first address of the data packet with Ethernet frame format in the buffer area of the forwarding processor, and transmits the data packet with Ethernet frame format to the receiver processor; step 140, the receiver processor receives the data packet with Ethernet frame format. The present invention realizes the quick forwarding of the data, and reduces the load of the forwarding processor and the delay of the data transmission.

Description

technical field [0001] The present invention relates to the system that adopts multiprocessor to cooperate to process data in the field of communication, especially relates to a kind of when adopting RapidIO (rapid input and output) agreement and Ethernet agreement to carry out data transmission among multiprocessors, data passes through RapidIO port to Ethernet The method of port data transfer. Background technique [0002] In current communication systems, multiple processors are generally used to process data, so a large amount of data needs to be transmitted in the system. The Ethernet protocol and the RapidIO protocol are two high-speed data transmission protocols, and the use of the integrated Ethernet port and RapidIO port of the processor chip for high-speed data transmission within the board or between board-level chips has become more and more widely used. . [0003] For data transmission between multi-processors, it may be necessary to have a certain processor i...
