PURPOSE:To read out efficiently a vector data by reducing a wasteful memory overhead, when reading out in multiple the vector data on a main storage by shifting a reference range little by little. CONSTITUTION:A data read-out from a main storage is executed only once of A (1-m+2), and a read-out data distributing circuit distributes a data required for correspondence of each vector register basing on an information such as a head element number, a vector length, etc. For instance, the head element number of the data transferred to vector registers R1, (R1+1)-(R1+3) become 1, 2, 2 and 3, respectively, and the vector length becomes (m). According to such a method, it does not occur that the same element data is overlapped and read out, and an efficient memory access is executed. Also, although a read-out port from the main storage is only one, the data can be stored simultaneously in plural vector registers, threfore, the data required for an arithmetic can be prepared quickly. |
