Abstract
PURPOSE: To increase the efficiency of utilization of an address conversion buffer by suppressing a hash bit at one part of an address space name only when a logic address indicates shared space in a virtual memory data processing system.
CONSTITUTION: Virtual address register LA is provided with areas for segment number SN, page number PN and displacement D in a page, register JP holds an address space name during current execution, and address generating circuit ADG uses number SN of LA and the hash bit of JP to attain access to address conversion buffer TLB. Then, TLB includes information on the logic address, actual address, address space name, etc., and has compartments 0 and 1 and detecting circuit ADM compares addresses of a couple of entries addressed by the logic address from LA, address space name from JP and ADG to the space name and sends out a corresponding actual address when the comparison result shows identity. Then, a fixed hash bit is suppressed and outputted at the time of a shared segment.
