Problems solved by technology

[0003] However, if the peak power consumption is too large, the manufacturing requirements for the hardware devices using the TURBO decoder will be higher. For example, in order to cope with the high peak power consumption, the power chip must use complex circuits or design structures so that the power chip can withstand High peak power consumption, however, the more complex the circuit or design structure, the higher its manufacturing and design costs, which will increase the manufacturing cost of the device

Embodiment 1

[0021] An embodiment of the present invention provides a method for controlling the power consumption of a TURBO decoder, such as figure 1 shown, including:

[0022] Step 101, determine the size of the transport block.

[0023] Step 102: Determine the number of iterations required by the TURBO decoder to process the transport block according to the size of the transport block, so as to control the amount of computation required by the TURBO decoder to process the transport block.

[0024] Specifically, in this embodiment, the TURBO decoder can determine a preset value of the amount of operation, and the preset value of the amount of operation can be automatically set by the TURBO decoder according to the specific environment or preset by a technician, and in The preset value of the amount of computation will not change when the TURBO decoder decodes the data packet. For example, for the HSPA (High-Speed ​​Packet Access) channel in 3GPP, the preset value of the amount of compu...

Embodiment 2

[0028] An embodiment of the present invention provides a method for controlling the power consumption of a TURBO decoder, such as figure 2 shown, including:

[0029] Step 201, determine the size of the transport block.

[0030] Wherein, in the practical application of the TURBO decoder, the calculation amount of the TURBO decoder is proportional to the size of the transport block currently processed by the TURBO decoder and the number of iterations when the TURBO decoder processes the transport block.

[0031] Further, the relationship between the calculation amount required by the TURBO decoder for processing the transport block, the size of the transport block and the number of iterations required for processing the transport block is:

[0032] C≥TB_SIZE*INTER_TIME, where C is a preset value of computation, TB_SIZE is the size of the transport block, and INTER_TIME is the number of iterations required by the TURBO decoder to process the transport block.

[0033] For each ...
