Abstract
In outputting data input in units of a bits in units of b bits (a<b) using a memory for storing data, the reading of the memory is controlled such that a first item of b-bit data is formed in so as to include all of a first item of a-bit data. Items of b-bit data succeeding the first item of the b-bit data are formed by using b/k bits taken from each of k items of a-bit data of those items of the a-bit data succeeding the first item of a-bit data, and the portion of the first item of b-bit data other than the first item of a-bit data is formed of (a-b/k) bits in the succeeding items of a-bit data (where a, b and k are integers), whereby the units in data processing can be changed by a simple construction and improvement in data transfer efficiency can be achieved.
