Example Embodiment

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] In view of the situation that variable length data frames and random processing of variable length data frames are often generated in the baseband signal processing system of the communication system, the present invention proposes a storage unit suitable for such irregular data access. The unit is cascaded into the baseband signal processing system, so that each signal processing data unit in the system can process such irregular data in the same way as regular data, simplifying the complexity of the logic circuit design of each signal processing data unit , Improve the data processing capacity of the entire baseband processing system.

Abstract

The invention discloses a device for improving the baseband signal processing capacity of a satellite navigation terminal receiver. The device comprises a frame data storage unit, a base address storage unit, a frame data length storage unit and a logic control unit, wherein the frame data storage unit is used for storing frame data information produced during baseband signal processing; the base address storage unit is used for storing base addresses of real physical space of data frames; the frame data length storage unit is used for storing the information of the length taking each byte of each data frame as a unit; and the logic control unit generates storage state information for an external port. The device is connected to a baseband signal processing system through the storage units in a cascading manner, signal processing data units in the system can process data without specific laws in the same manner for processing regular data, design complicity of logic circuits of the signal processing data units is simplified, and the data processing capability of the whole baseband processing system is improved.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a device for improving the baseband signal processing capability of a satellite navigation terminal receiver, and also to a method at the same time. Background technique [0002] The baseband signal processing system of the communication system often produces variable-length data frames and random processing of variable-length data frames. The processing of such data usually has no specific data processing rules, which is not conducive to the realization of logic circuits. Even through comparison The implementation of complex logic circuits will also interrupt the pipeline processing of the entire signal processing system due to irregular data processing, resulting in low signal processing throughput. Contents of the invention [0003] One of the purposes of the present invention is to provide a device capable of improving the baseband signal processing capability of the ...
