Abstract

The invention provides a method for transmitting data by a DSP chip and a device thereof. The method comprises the following steps: setting a sending data buffer area and a receiving data buffer areain a network controller; when data needs to be sent, writing the to-be-sent data into the sending data buffer area so that the network controller sends the to-be-sent data through a network; and whenthe data needs to be received, running an interrupt service program, and reading the to-be-received data received by the network controller through the network from the data receiving buffer area. According to the scheme, the DSP chip without an integrated network interface can transmit data through a network.

Description

technical field [0001] The invention relates to the field of chip technology, in particular to a method and a device for transmitting data by a DSP (Digital Signal Processing, digital signal processing) chip. Background technique [0002] DSP chip is a microprocessor with a special structure, which can process digital signals quickly, so it is widely used in many fields such as image processing and communication. [0003] However, in the prior art, some DSP chips cannot transmit data through the network because they do not have an integrated network interface inside. Contents of the invention [0004] The invention provides a method and a device for transmitting data by a DSP chip, so that the DSP chip without an integrated network interface can transmit data through the network. [0005] First aspect, the present invention provides a kind of method for DSP chip transmission data, comprising: [0006] Set a sending data buffer and a receiving data buffer in the network c...
