Abstract

The invention relates to the field of digital signal processing, and discloses a cumulative summation method based on dual-port caching. The method includes the steps of configuring dual ports according to the length and bit number of a summation sequence, setting the Memory Type in an IP core as the True Dual Port RAM type, matching the bit width of data input / output by the dual ports with the digitalizing bit number of the summation sequence, setting the depth of the dual ports, generating the dual ports after configuration is completed, predicting the maximum value of the summation result SUM, setting a corresponding bit number, making a module reset, and conducting summation according to the input data DIN and the output data DOUT after reset is completed. According to the method, the summation of the long sequence is achieved, lots of hardware expenses can be saved, and high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a dual-port buffer-based accumulation and summation method and device. Background technique [0002] Spread spectrum communication is a very important anti-interference communication technology, which has many advantages such as strong anti-interference ability and good signal concealment. Spread spectrum technology is widely used in military and civilian communication fields. With the improvement of key indicators such as system range and 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 spread spectrum codes results in the accumulation of a large amount of sample data involved in signal despreading. Similarly, the threshold technology in the signal processing of the spread spectrum system also...
