TABLE 3-1:
The MIPS architecture defines that the result of a mul-
tiply or divide operation be placed in the HI and LO reg-
isters. Using the Move-From-HI (MFHI) and Move-
From-LO (MFLO) instructions, these values can be
transferred to the General Purpose Register file.
In addition to the HI/LO targeted operations, the
MIPS32 architecture also defines a multiply instruction,
MUL, which places the least significant results in the
primary register file instead of the HI/LO register pair.
By avoiding the explicit MFLO instruction, required
when using the LO register, and by supporting multiple
destination registers, the throughput of multiply-inten-
sive operations is increased.
Two other instructions, multiply-add (MADD) and multi-
ply-subtract (MSUB), are used to perform the multiply-
accumulate and multiply-subtract operations. The
MADD instruction multiplies two numbers and then adds
the product to the current contents of the HI and LO
registers. Similarly, the MSUB instruction multiplies two
operands and then subtracts the product from the HI
and LO registers. The MADD and MSUB operations
are commonly used in DSP algorithms.

3.2.3
In the MIPS architecture, CP0 is responsible for the vir-
tual-to-physical address translation, the exception con-
trol system, the processor’s diagnostics capability, the
operating modes (Kernel, User, and Debug), and
whether interrupts are enabled or disabled. Configura-
tion information, such as presence of options like
MIPS16e, is also available by accessing the CP0
registers, listed in Table 3-2.
