Abstract

The present invention relates to the field of digital signal processing, discloses a kind of accumulative summation method based on dual-port cache, the method includes: according to the length and the number of digits of the summation sequence, the dual-port is configured, and the Memory Type in the IP core is set to True Dual Port RAM type, the bit width of the dual-port input / output data matches the quantization digits of the summation sequence, set the dual-port depth, and generate the dual-port after the configuration is completed; estimate the maximum value of the summation result SUM , set the corresponding number of digits; reset the module; after the reset is completed, summation is performed according to the input data DIN and output data DOUT. According to the accumulative summation method through the double-port buffer, the invention realizes the summation of a long sequence, and can save a large amount of hardware expenses, and has strong practical value.

Description

Technical field [0001] The present invention relates to the technical field of digital signal processing, in particular to a method and device for accumulation and summation based on dual-port buffering. Background technique [0002] Spread spectrum communication is a very important anti-interference communication technology. It has many advantages such as strong anti-interference ability and good signal concealment. Spread spectrum technology is widely used in military and civilian communications. With the improvement of the requirements for key indicators such as the range of the system and the receiving sensitivity, the spread spectrum system is also constantly developing in the direction of increasing the number of spread spectrum codes and increasing the spread spectrum gain. The increase in the number of bits of the spreading code leads to the accumulation of a large number of sample data when despreading the signal. Similarly, the threshold technology in the signal proce...
