7. Memory Management Unit (MMU)
7.5.4
In an instruction access, this LSI searches the ITLB. If it cannot find the necessary address
translation information (ITLB miss occurred), the UTLB is searched by hardware, and if the
necessary address translation information is present, it is recorded in the ITLB. This procedure is
known as hardware ITLB miss handling. If the necessary address translation information is not
found in the UTLB search, an instruction TLB miss exception is generated and processing passes
to software.
