3.3 CPU Register
3.3.1 Overview of register file
Figure 3-4 shows the CPU registers of the VR4100. The bit width of these registers is determined by the
operation mode of the processor (in 32-bit mode: 32 bits, in 64-bit mode: 64 bits).
Of the thirty-two general-purpose registers of the V
R
4100, the following two registers have special meanings:
Register r0
:
The contents of this register are always 0. To discard the result of an operation, this register
can be coded as the target of the instruction. If the value 0 is needed, this register can be
used as a source register.
This is a link register for the JAL and JALR instructions. Therefore, do not use this register
with any other instructions.
Register r31 :
The two multiplication/division registers (HI and LO) store the result of multiplication or sum-of-products
operation, or quotient (LO) and remainder (HI) resulting from division.
However, because the V
R
4100 does not support floating-point operation instructions, the thirty-two floating-
point general-purpose registers (FGRs), which are provided in the V
R
4200
and V
R
4400
, are not provided in
the V
R
4100.
Remark
The load link bit (LL bit) used for the multi-processor system synchronization instructions (LL and SC)
supported by the V
R
4200 and V
R
4400 is not provided in the V
R
4100 (refer to
3.4 (2) Deletion of multi-
processor instructions
).
