UWB ultra-wideband receiving baseband SOC system on chip based on asip

Abstract

The invention discloses an ASIP-based UWB receiving baseband SOC, which comprises a data processing system composed of a front-end data stream co-processing unit and an ASIP processing unit. The front-end data stream co-processing unit acquires an ultra-wideband signal data stream, a lead code preprocessing module in the front-end data stream co-processing unit operates the data stream to obtain amaximum correlation value, a minimum correlation value and a maximum correlation value position, and a data decoding preprocessing module performs decoding preprocessing on PHR and PSDU parts of dataframes in the data stream; and an ASIP internal scalar processing unit calculates information of a ultra-wideband signal according to the maximum correlation value, the minimum correlation value andthe position of the maximum correlation value, and the ASIP scalar processing unit and a vector processing unit decode the decoded and preprocessed data to obtain PHR and PSDU parts of the data framesin the data stream. According to the invention, high performance and low power consumption of the chip are ensured, and the chip can be rapidly and flexibly realized in ASIP.

Description

technical field [0001] The invention relates to the field of UWB baseband chip data processing systems, in particular to an ASIP-based UWB ultra-wideband receiving baseband SOC system on chip. Background technique [0002] With the development of UWB technology, UWB technology has gradually become the mainstream technical solution for indoor high-precision positioning. The UWB industry standard has also changed. The IEEE 802.15.4z protocol defines new features based on the original standard, which can improve security, lower power consumption, and longer transmission distance. The new protocol puts forward higher requirements for UWB receiver design, higher speed and lower power consumption. At the same time, due to the continuous development of UWB industry standards, it also requires higher flexibility in new receiver design. [0003] The existing UWB receiver architecture is generally a data stream processing system composed of a front-end data stream co-processing unit ...
