Method and vector computing unit for implementing de-scrambling and de-spreading, and computer storage medium

A vector computing unit for implementing de-scrambling and de-spreading, comprising:

• a vector register file, a reading interface operation unit and a vector multiplying and adding unit, wherein
• the vector register file is configured to store baseband data, results obtained by multiplying the baseband data and corresponding de-scrambling and de-spreading codes, inter-row data accumulation results and intra-row pairwise data accumulation results;
• the reading interface operation unit is configured to read the baseband data from the vector register file and perform data transformation on the baseband data according to the corresponding de-scrambling and de-spreading codes, or, read data obtained by multiplying the baseband data and the de-scrambling and de-spreading codes or accumulated data from the vector register file and perform data position exchange required by addition of every two adjacent pieces of data;
• and
• the vector multiplying and adding unit is configured to perform addition processing on the data transformed by the reading interface operation unit and store an obtained result into the vector register file, and
• is further configured to read from the vector register file a row of data obtained by the complex multiplication, accumulate every two adjacent pieces of data to obtain a half row of data, store the obtained data back into the vector register file, continue reading a previous accumulation result from the vector register file or a previous accumulation result reserved in a result register of the vector computing unit, accumulate every two adjacent pieces of data in the previous accumulation result to obtain a ¼ row of data, continue accumulation to finally obtain one piece of accumulated data;
• and continue the accumulation processing on other rows of data to implement accumulation of each row of data obtained by the complex multiplication in the vector register file.
