Abstract

A translation lookaside buffer (TLB) that is shared by instructions and data, and it contains a copy of the instruction address register (IAR) so that the TLB can feed the instruction processing unit (IPU) sequential instructions from main storage without stopping to request the address from IPU, then the IAR can be used as an additional TLB entry to improve system performance by increasing the TLB hit ratio.
