Move the high-order longword from accumulator
|
MVFACHI
|
|
MoVe From ACcumulator HIgh-order longword
|
[Syntax]
(2) | MVFACHI src, Asrc, dest [V2.01.00 or later] |
[Operation]
(1) | dest = (signed long) (ACC >> 32); |
tmp = (signed 72bit) Asrc << src;
dest = (signed long) (tmp >> 32); [V2.01.00 or later]
[Function]
(1) | This instruction moves the higher-order 32 bits of the accumulator (ACC) to dest. |
(2) | The MVFACHI instruction is executed according to the following procedures. |
Processing 1:
The value of the accumulator is shifted to the left by zero to two bits as specified by src.
Processing 2:
This instruction moves the contents of bits 63 to 32 of the accumulator (ACC0 or ACC1) to dest.
You can assemble assembly-language code that includes this instruction if you have specified the assembler option -isa with selection of the instruction set of the RXv2 or a later version. [V2.01.00 or later]
