TWO-DIMENSIONAL ORTHOGONAL CONVERTER

摘要

PURPOSE:To secure about the double processing speed with a two-dimensional orthogonal converter by providing two systems of means which performs the inner product operations among the vectors having the number of elements equal to 4. CONSTITUTION:The m-th line of TA is calculated after the processing X(m) and therefore the processing Y(m) is calculated among the operations of TATT based on the TA calculation data. In the same way, the processing Y(m) is carried out within the calculation of (TA)TT based on the TA calculation data since the m-th line of TA is calculated after the processing X(m). Thus two systems of means are provided for calculation of the inner products carried out among the vectors having the number N of elements. Thus the processing X(m+1) and the processing Y(m) are simultaneously calculated after the processing X(m). Then the pipeline processing is attained between both processings X(m) and Y(m).
