Abstract
A two-dimensional array is stored in a first storage memory. A data accessing direction of the first storage memory is in a row direction. A method for reading data in the two-dimensional array in a column direction contains reading a plurality of data sets in the array from the first storage memory; performing a calculating operation on a first data set of the plurality of data sets; storing remaining data sets of the plurality of data sets into a second storage memory; and sequentially reading and applying the calculating operation on the remaining data sets stored in the second storage memory.
Claims18
A method for reading data in a two-dimensional array in a column direction, the two-dimensional array being stored in a first storage memory, a data accessing direction of the first storage memory being in a row direction, and the method comprising the following steps:
- reading a plurality of data sets in the column direction of the two-dimensional array from the first storage memory;
- performing a calculating operation on a first data set of the plurality of data sets;
- storing remaining data sets of the plurality of data sets into a second storage memory;
- and
- sequentially reading and applying the calculating operation on the remaining data sets stored in the second storage memory.
