Embodiment approach

[0051] Under the preferred embodiment, continue to refer to figure 1 , before acquiring the multiply-accumulate operation instruction, the implementation method of the programmable digital filter also includes:

[0052] S101. Obtain and store a data loading instruction;

[0053] S102. Load the input update configuration data and update configuration coefficients into corresponding storage locations in the general register set.

[0054] Through the above steps S101 and S102, the configuration of the data in the general register group can be performed, so as to configure the corresponding data for the filters of the multi-mode terminal in various modes. In the embodiment of the present invention, the transfer function adopted by the multi-mode terminal in a corresponding mode may be the corresponding processing function provided by the prior art, and the present invention does not impose any limitation on this.

[0055] In a preferred embodiment, when the update configuration da...

Abstract

The invention discloses a programmable digital filtering implementation method, an apparatus, a baseband chip and a terminal thereof. The method comprises the steps of acquiring and storing a multiply-accumulate operation instruction; reading corresponding configuration data and a configuration coefficient that are stored in a general-purpose register block to user configuration according to the multiply-accumulate operation instruction; and carrying out a multiply-accumulate operation based on the configuration data and the configuration coefficient. The digital filtering device with microprocessor architecture can be used for achieving any multiply-accumulate operation. Especially in the multi-mode mobile terminal baseband processing, a set of filter resources is used for replacing different filter resources in multiple modes, so that the area of the device is greatly reduced. Different types of filter can be programmed flexibly, and through the processing of software radio, system resources can be saved and energy consumption can be reduced to some extent.

Description

technical field [0001] The present invention relates to the technical field of digital signal processing, in particular to a programmable digital filtering implementation method, device, baseband chip and terminal thereof. Background technique [0002] In communication systems, FIR (Finite Impulse Response, finite impulse response) filters and IIR (Infinite Impulse Response, digital filters) digital filters are commonly used. Among them, FIR filters are often used for sampling and interpolation, and their mathematics The formula is as follows: [0003] [0004] In addition, the time domain formula of the IIR filter is as follows: [0005] y ( n ) = Σ k = 0 N - 1 b k x ( n - ...
