摘要： A kind of folding systolic array architecture for a CFRS decoding circuit that applies to a cell search in a wideband code division multiple access system. The invention involves using a systolic array for its decoding circuit and using a kind of folding technology to reduce the area of the systolic array. The systolic array for the decoding circuit comprises an input pattern generator, a processing element array designed in the form of a systolic array and a boundary processing element array. Given the skewed-form output results required by the systolic array and generated by the input pattern generator, the processing element array makes a set of correlating comparisons, and outputs the results of the correlating comparisons to the boundary processing elements, so as to acquire the decoding results required by the CFRS decoding. The results indicate the frame boundary and scrambling code groups of the cell search in a wideband code division multiple access system.

摘要： The present invention discloses a configurable hierarchical comma-free Reed-Solomon decoding circuit and a method thereof. The design is based on an original hierarchical parallel architecture which not only completes a decoding process faster than conventional decoder, but also utilizes less hardware to perform various algorithms with less power consumed. The architecture of the present invention has higher decoding rate than the conventional systolic architecture by a cycle ratio of 22 to 94. Further, the present invention does not require the use of ROM to store 64 sets of codewords and uses logic gates less than one fourth of the logic gates than conventional systolic architecture. As a result, the circuit of the present invention occupies less area than the conventional architecture. The circuit of the present invention is also configurable for different applications, so it can always find an optimal compromise between speed and power consumption for various decoding requirements.
