Abstract

The invention provides a method for realizing accelerated computing and high-speed network data transmission by embedded equipment, and solves the problem that the network transmission rate of a network card is increased by designing a network transmission method in order to meet the requirement of accelerated calculation under the condition that a heterogeneous multi-core processor of the embedded equipment realizes high-speed calculation. The main method comprises the steps that a microprocessor core of the heterogeneous multi-core processor of the embedded device is responsible for receiving input data and parameter data of acceleration calculation, then an acceleration calculation core of the heterogeneous multi-core processor is called for acceleration calculation, and finally calculated result data are sent out through the Ethernet. According to the method provided by the invention, the network packet without the TCP / IP packet header is directly sent and received through the Ethernet in a bare board manner, so that the network transmission rate is matched with the calculation rate of the acceleration calculation module, and the overall performance is improved.

Description
