Embodiment Construction
[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0042] The present invention aims at the problem that when the PCI-E high-speed transmission technology is adopted in the prior art, the transmission can only be carried out for specific signals or specific formats, and the transmission mode is single, so it is difficult to meet the needs for multiple signal access, and provides a A signal processing method and a signal processing device based on a PCI-E interface.
[0043] Such as figure 1 As shown, the signal processing method in the embodiment of the present invention includes:
[0044] Step 10, obtaining multiple input signals of different types;
[0045] Step 20, after converting each input signal in the multiple input signals to satisfy the transaction layer packet (TLP, TransactionLayerPack...

The invention provides a PCI-E (Peripheral Component Interconnect Express) interface based signal processing method and a PCI-E interface based signal processing device, and belongs to the field of signal processing. The signal processing method comprises the steps of obtaining different types of input signals; respectively converting each type of the input signals into a TLP (Transaction Layer Packet) message which satisfies a PCI-E bus format and buffering the TLP message; performing arbitration control for the buffered TLP message of each type of the input signals; and outputting the TLP message of each type of the input signals by a PCI-E controller based on a result after the arbitration control. According to the scheme above, transmission control for multiple types of the access signals is realized by utilizing the arbitration control. Through the way, setting of the PCI-E interface is reduced, and the equipment interconnecting efficiency is improved.
Description
technical field [0001] The invention relates to the field of signal processing, in particular to a signal processing method and a signal processing device based on a PCI-E interface. Background technique [0002] PCI-E (Peripheral Component Interconnect Express, the external interconnection equipment standard for high-speed transmission) technology was proposed by Intel in 2001, and at the end of 2002, it joined forces with AMD, DELL, IBM and other companies to form a technical specification, named PCI-E, which is the third generation Standard for the I / O bus. PCI-E adopts the current popular point-to-point serial connection in the industry, each device has its own dedicated connection, does not need to request bandwidth from the entire bus, and can increase the data transmission rate to a very high frequency, PCI-E Dual-simplex connections provide higher transfer rates and quality. The PCI-E interface varies according to the requirements of the bus interface on the bit wi...
