The following supervisor-level SPRs are implementation-specific to the 603R:
Figure 12-1
to the right of the SPRs indicate the number that is used in the syntax of the instruction operands
to access the register.
– The Time Base register (TB) is a 64-bit register that maintains the time of day and
– The Processor Version Register (PVR) is a 32-bit, read-only register that identifies

– The DMISS and IMISS registers are read-only registers that are loaded
– The HASH1 and HASH2 registers contain the physical addresses of the primary and
– The ICMP and DCMP registers contain a duplicate of the first word in the Page Table
– The Required Physical Address (RPA) register is loaded by the processor with the
