The invention discloses a communication method between data processors and memory equipment, and related devices, thus realizing direct communication between a plurality of data processors, reducing protocol expenditure in certain level, reducing transmission delay, and improving transmission efficiency; in some feasible embodiments, the method comprises the following steps: a control module obtains an order signal sent by the first data processor through a notification bus, wherein the order signal is used for indicating the first data processor to obtain read-write control authority of the memory equipment, and the first data processor is a random data processor of the plurality of data processors; the control module obtains the order signal of the first data processor, and sends a switch signal to a switch circuit so as to indicate the switch circuit to switch circuits, so the communication can be set up only between the first data processor and the memory equipment.
Description
technical field [0001] The invention relates to the field of computer and communication technologies, in particular to a communication method and a related device for a data processing device and a memory device. Background technique [0002] With the increasing data traffic in the data center, the server's demand for fast and large-capacity data communication is getting stronger and stronger. High-density computing has become one of the main development trends of new servers, and the number of integrated processors per unit space is increasing. For example, generally 2-4 Xeon x86 processors can be integrated on the motherboard of a 1RU / 2RU (Rack Unit, cabinet unit) standard server. In addition, AMD's SeaMicro server has integrated 384 Atomx86 processors in a 10RU chassis. How to realize fast data exchange and communication among multiprocessors has become an urgent problem to be solved. [0003] The existing communication mechanism relies on communication transmission pr...
