Problems solved by technology

[0007] Therefore, in the multi-channel data processing method 6 adopted in the prior art, no matter whether the data is received or not, the query process is always carried out, which increases the power consumption of the chip; and only the first 8 cycles (because there are only 8 channels) are processing in the 32 cycles. Data, the next 24 cycles are idle
In addition, the continuous query processing cycle of each channel is fixed at 32 cycles, so the synchronization processing of data is relatively complicated, and the caching method of the 2-level cache structure must be adopted to ensure that no data is lost

Embodiment Construction

[0045] The core idea of ​​the present invention is to design the query mode of multi-channel data as an event-triggered query mode, that is, when no data is received by each channel, the query process stops, and when each channel receives data, the multi-channel data query process is triggered to start , in the multi-channel data query process, the data of each channel is queued, such as Figure 6 As shown, the processing method of the serial-to-parallel conversion part is exactly the same as that of the prior art, but in the processing of the synchronous processing part, only the first-level cache of the data is sufficient.

[0046] The present invention will be further described now in conjunction with accompanying drawing, the device of multi-channel data processing of the present invention, such as Figure 6 , Figure 7 and Figure 9 As shown, it includes the serial-to-parallel conversion part, the synchronization processing and data unpacking part and the multi-channel ...

Abstract

The present invention relates to a multi-channel data processing method and device. The present invention designs the multi-channel data query mode as an event-triggered query mode, that is, when no data is received by each channel, the query process stops, and when a certain When a channel or several channels receive data, the multi-channel data query process is triggered to start. During the multi-channel data query process, the data of each channel is queued and processed, and in the synchronous processing part, only the data is cached at the first level. . Therefore, the present invention reduces the power consumption when the data processing chip performs multi-channel data processing, and simultaneously reduces the data processing complexity of the data processing chip.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a method for realizing multi-channel data processing. Background technique [0002] In data communication, it is often necessary to process events such as interrupts and data transmission of each channel. For the communication system, the demodulation module used to process this type of data receives uplink TPC (transmission power control) data from 8 demodulation ports, and the 8 ports are independent of each other. [0003] The multi-channel processing process adopted by the demodulation module is as follows: figure 1 As shown, among them, clk_dm0: indicates the serial port clock signal of channel 0 in the 8 channels, and the clocks of the 8 channels have the same frequency but different phases; fsm_dm0: indicates the demodulation frame header indicator signal of channel 0 in the 8 channels, indicating The new demodulation frame transmission starts, and the minimum...
