Communication device and communication method

Abstract

The present invention relates to a communication device comprising at least one channel unit. Each channel unit comprising a first interface unit, a second interface unit, a first FIFO unit, a secondFIFO unit, and a storage unit. The first interface unit comprises a first control register, and the first control register is suitable for receiving quantity information and position information of to-be-transmitted data. The second interface unit comprises a second control register, and the second control register is suitable for receiving the quantity information of the to-be-transmitted data from the first control register and receiving the position information of the storage area allocated to the to-be-transmitted data by the receiving end. The first FIFO unit is connected with the first interface unit and is suitable for acquiring quantity information and position information of to-be-transmitted data from the first control register. The second FIFO unit is connected with the second interface unit, and is suitable for obtaining the quantity information of the to-be-transmitted data from the second control register. And the storage unit is connected with the first FIFO unit and thesecond FIFO unit.

Description

technical field [0001] The invention relates to a communication device which can realize high-speed communication between a sending end and a receiving end. Background technique [0002] In the field of integrated circuits, in order to meet the needs of communication, multimedia and digital processing, the system-on-a-chip (SoC, System-on-a-chip) has not only integrated a core (Core) or processor (CPU), but more The most important thing is to integrate multiple processors into the system, and even need to work together with off-chip processors. For example, electronic devices such as personal computers and smart phones often adopt a multi-processor operation mode. In a system containing two or more processors, the processors can exchange data with each other and share resources such as memory, I / O devices, controllers, and external devices. Through the control of the operating system, comprehensive parallelism at all levels of jobs, tasks, programs, arrays and their elemen...

Problems solved by technology

Although the communication device 20 using this communication method has relatively high efficiency, each processor needs to expose a part of its memory address space to allow other processors to modify the memory address space, so there are risks such as data tampering, and the system design does not Reasonable
