如果在MSR(机器状态寄存器)中可用的浮点位被禁用，将尝试执行一个浮点指令。
An attempt was made to execute a floating point instruction when the floating point available bit in the MSR (machine status register) was disabled.
在两种模式下，设定64位寄存器的指令将影响所有64位。
In both modes, instructions that set a 64-bit register affect all 64 bits.
为了解决这一问题，乘法指令只使用每个32位的最低有效的16 位以便结果能够放进整个 32 位寄存器内。
To combat the problem, multiplication instructions only use the least-significant 16 bits of every 32-bit value so that the result will fit in the full 32-bit register.
与使用32 位的寄存器相比，由于使用了 64位的寄存器，要执行相应的计算工作，只需使用更少的指令。
These can, by virtue of 64-bit registers, perform computations with fewer instructions than with 32-bit registers.
LK位指定了下一个顺序指令的地址是否作为子例程调用的返回地址保存在链接寄存器中。
The LK bit specifies whether the address of the next sequential instruction is saved in the Link Register as a return address for a subroutine call.
你可以使用不精确的指令和操作数并符合32位寄存器RA和RB。
You can use imprecise commands and operands and matching 32-bit registers ra and RB.
一个八位的指令寄存器也只能确定256种不同的操作以及对于这些操作的修改。
An 8-bit instruction register can only specify 256 different operations and variations on operations.
一个八位的指令寄存器也只能确定256种不同的操作以及对于这些操作的修改。
