我对汇编语言实在是没辙，如下：
SWORD get_svalue(BYTE k)
// k>0 always
// Takes k bits out of the BIT stream (wordval), and makes them a signed value
{
_asm {
xor ecx, ecx
mov cl,k
mov eax,[wordval]
shl eax,cl
shr eax, 16
dec cl
bt eax,ecx
jc end_macro
signed_value:inc cl
mov ebx,[start_neg_pow2]
add ax,word ptr [ebx+ecx*2]
end_macro:
}
}
WORD WORD_hi_lo(BYTE byte_high,BYTE byte_low)
{
_asm {
mov ah,byte_high
mov al,byte_low
}
}
WORD lookKbits(BYTE k)
{
_asm {
mov dl, k
mov cl, 16
sub cl, dl
mov eax, [wordval]
shr eax, cl
}
}
请高手帮我把上述3个函数用C语言实现，急用，谢谢！ |
