Preliminary Data Sheet
3.4 System Control Coprocessor (CP0)
CP0 supports memory management, address translation, exception processing, and privilege operations. CP0 has
the registers shown in Table 3-1, and a 32-entry TLB.
The basic configuration of the CP0 registers of the V
R
4102 is the same as that of the V
R
4300 and V
R
4400. However,
because the number of entries of TLB, page size, cache size, physical address space, and system interface differ
between the V
R
4102 and V
R
4300/V
R
4400, the bit configuration and setting differ. For details, refer to
V
R
4102 User’s
Manual
.
3.4.1 CP0 registers
All the CP0 registers that can be used with the V
R
4102 are listed below. Writing to or reading from an unused register
(RFU) is undefined. In the 32-bit mode, the high-order 32 bits of 64-bit registers are masked.
