Problems solved by technology
However, there are many problems in the use of common processing components: first, the cost of using current general-purpose processing components is often high; second, it depends to a great extent on the product development route of the chip supplier and its product requirements; General-purpose processing components cannot handle more complex wireless environments such as LTEA, microwave transmission, multi-mode fusion processing, etc., nor can they adapt to the development requirements of such more complex wireless environments

The invention provides a device and a method for baseband processing. A cubic flow processing device for the baseband processing comprises an instruction obtaining and decoding device, an instruction distribution device and a special processing device. The instruction obtaining and decoding device is used for obtaining and decoding an instruction from an instruction cache device so as to obtain a to-be-processed instruction. The instruction distribution device is used for judging whether the to-be-processed instruction is a specific instruction or not, and when the to-be-processed instruction is judged to be the specific instruction, the instruction is issued to the special processing device. The special processing device is used for obtaining data from a register array of the cubic flow processing device and a self corresponding data area when the to-be-processed instruction is received, so that the data can be processed, and a processing result is enabled to be stored into the data area. The device and the method for the baseband processing have the advantages that the special processing device is used for processing the specific instruction, particularly a self-defined complicated instruction, and the efficiency for processing the specific instruction is improved significantly.
Description
technical field [0001] The present invention relates to the communication field, in particular to a device and method for baseband processing. Background technique [0002] Software-Defined Radio (SDR, Software-Defined Radio) is used to implement efficient multi-mode baseband processing schemes in wireless base stations. However, the increasing complexity of multi-antenna transmission technology and the tightening of energy budgets are challenging the SDR mode. [0003] The processing components usually used for baseband processing are mostly based on multi-core DSPs and large FPGAs. Such as the latest DSP-based TurboNyquist (TMS320C6618) system-on-a-chip, which includes 4 DSP cores and multiple co-processors, such as Bitlevel processors, FFT and TurboDecoder, etc., the chip can handle 20MHz bandwidth and four antenna arrays. However, there are many problems in the use of common processing components: first, the cost of using current general-purpose processing components is...
