Abstract
PURPOSE: To make it possible to take out data extending over two adjacent blocks by one access processing, by dividing and storing this data in two buffer memories and taking out it at a time by the control of a control means.
CONSTITUTION: Even-side buffer memory 1-0 and odd-side buffer memory 1-1 store even-numbered and odd-numbered blocks respectively and can be accessed independently of each other. Buffer memory address control part 5 controls selectors 4-0 and 4-1 on a basis of address information, read direction information and access length. For example, in case that the access address exists in the even side and the read direction is the address increment direction and access length is eight bytes, the access address is given to memory 1-0 as it is, and an address obtained by increasing the access address by "1" is given to memory 1-1. Thus, desired line-cross eight-byte data can be taken out at a time.
