Device, system and method for transmitting data

Abstract

Embodiments of the present invention provide a data transmission apparatus, system, and method. The apparatus includes: a data transit module, configured to read configuration information of a first sending buffer of a first processor core, and when the configuration information indicates that the first sending buffer stores data to be transmitted to a receiving buffer of a second processor core, control a DMA module to transmit the data from the first sending buffer to the receiving buffer, and set interrupt information; and an interrupt management module, configured to read the interrupt information, and when the interrupt information indicates that an interrupt needs to be triggered to the second processor core, control a multi-core interrupt controller to trigger the interrupt to the second processor core, to enable the second processor core to process the data in the receiving buffer.

Description

technical field [0001] The present invention relates to the fields of computer and communication, and in particular, to a device, system and method for transmitting data. Background technique [0002] At present, whether it is a mainframe or a personal computer (Personal Computer, PC) with an x86 architecture, a multi-core architecture has begun to be developed. For example, two cores and four cores have become common configurations in today's PC field. In addition, with the rapid development of multimedia audio and video applications, the increasing demand for massive data processing, and the rapid development of processor technology, embedded microprocessors are also developing in the direction of two-core, four-core and more cores. It can be seen that from the most high-end server processors to embedded processors that are very sensitive to power consumption, all mainstream processor architectures have embarked on the road of multi-core. [0003] The data processing pro...

Problems solved by technology

The currently commonly used inter-core communication method is that the sending processor core or the receiving processor core itself is responsible for data transfer and interruption operations, which causes the consumption of each core in inter-core communication to increase with the increase in the amount of transmitted data. The continuous growth has caused some businesses to be unable to process normally, seriously reducing the business processing capability of the processor core
