第二，oword和yword操作数的大小是多少? [英] What are the sizes of tword, oword and yword operands?
问题描述
tword，oword和yword操作数的大小是多少，如 YASM手册?在相关说明中，这些名称是否有花招或基本概念?有没有办法为较大的单词大小赋予逻辑名称?
What are the sizes of tword, oword and yword operands, as used in the NASM/YASM manual? And on a related note, is there a trick or underlying idea to these names? Is there a way by which bigger word sizes are given logical names?
我知道，尽管系统之间的字长可能有所不同，但NASM word是2字节，dword是2字节(4字节)的两倍，qword是四字(8字节)，但是... tword是三词(6个字节)吗?对于oword和yword，我什至都没有想到合理的含义.
I know that while word sizes may differ between systems, a NASM word is 2 bytes, dword is double that (4 bytes), qword is a quad word (8 bytes), but... is tword a triple word (6 bytes)? And for oword and yword I can't even think of a plausible meaning.
请注意，这可能是一个简单的问题，但我找不到答案.在NASM和YASM手册中，甚至在DQ，DT，DY，RESQ，REST，RESY伪指令中也没有说明这些大小.我在某处读到MASM使用类似的系统，但也找不到任何内容.
Note that it is probably an easy question, but I couldn't find an answer. In the NASM and YASM manuals these sizes are not explained, not even at the DQ, DT, DY, RESQ, REST, RESY pseudo-instructions. I read somewhere that MASM uses a similar system, but could not find anything on that either.
根据答案，这是完整的列表:
Based on the answers, this is the complete list:
- 1个字节(8位):
byte，DB，RESB - 2个字节(16位):
word，DW，RESW - 4个字节(32位):
dword，DD，RESD - 8个字节(64位):
qword，DQ，RESQ - 10个字节(80位):
tword，DT，REST - 16个字节(128位):
oword，DO，RESO，DDQ，RESDQ - 32个字节(256位):
yword，DY，RESY - 64个字节(512位):
zword，DZ，RESZ
- 1 byte (8 bit):
byte,DB,RESB - 2 bytes (16 bit):
word,DW,RESW - 4 bytes (32 bit):
dword,DD,RESD - 8 bytes (64 bit):
qword,DQ,RESQ - 10 bytes (80 bit):
tword,DT,REST - 16 bytes (128 bit):
oword,DO,RESO,DDQ,RESDQ - 32 bytes (256 bit):
yword,DY,RESY - 64 bytes (512 bit):
zword,DZ,RESZ
