Title: Storage area control system using virtual address
Inventor: INOUE KAZUHISA
IPC: G06F12/08
Filed: 1989-03-28
Abstract: PURPOSE:To attain the allotment of a storage area range independently of a virtual address range and to freely change the allocating constitution of the storage areas by allocating the describers and areas. CONSTITUTION:A virtual area allocation means 12 takes out the corresponding describer section information to a designated area acquiring request by reference to a 1st allocation table 16. A describer control means 13 takes a describer out of a describer section table 17 based on the describer section information. A real area allocation means 14 refers to a 2nd allocation table 18 via a describer to extract the corresponding real area information. A describer setting means 15 sets a describer and the area instruction value to the table 17. As a result, a real storage area can be optionally allocated to a describer section. Thus the allocating constitution of the storage areas can be changed by changing the describer and the area allocation table without changing the virtual address.
