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.
