ABSTRACT:
A requesting processor issues an instruction containing a segmented virtual space identifier (VSID) and a shared-access or nonshared-access identifier. A single translation lookaside buffer is divided into TLB partitions which have corresponding directory registers. Each directory register has a first field for storing a VSID and a second field have bit positions respectively assigned to the processors of the system. If the instruction contains a nonshared-access identifier, a directory controller selects one of the registers whose second field contains all vacant bit positions and writes the VSID of the instruction into the register and sets a bit in a position assigned to the requesting processor. The controller detects a register having the same VSID and first and second bits in positions respectively assigned to the master and requesting processors, and resets the second bit. If the instruction contains a shared-access identifier, then the directory controller detects a first register having the same VSID and a bit in a position assigned to the master processor and a second register having the same VSID and a bit in a position assigned to the requesting processor, sets a bit in a position of the first register assigned to the requesting processor, and resets the bit of the second register.
