This instruction format provides up to three registers as source operands , and one target operand 這一指令格式提供至多三個寄存器作為源操作數(shù),以及一個目的操作數(shù)。
This instruction format provides up to two registers as source operands and up to two target operands 這一指令格式提供至多兩個寄存器作為源操作數(shù),至多兩個目的操作數(shù)。
Instructions convert the source operand in the source fpr into single - precision format before storing to the target word in storage 指令可以將源fpr中的源操作數(shù)在存儲到存儲器中目標字之前轉換為單精度格式。
This instruction format provides up to two registers as source operands , one immediate source , and up to two registers as target operands 這一指令格式提供至多兩個寄存器作為源操作數(shù),一個立即源,至多兩個寄存器作為目的操作數(shù)。
Some variations of this instruction format use portions of the target and source operand specifiers as immediate fields or as extended opcodes 這一指令格式的一些變種使用部分目的和源寄存器操作數(shù)說明符作為立即字段或作為擴展的操作碼。
