Bit-Reverse C Code
提供一下 u8 & u32 bit reverse C code
代碼:
static inline u32 u32_bit_reverse(u32 v)
{
u32 r = v;
int s = 31;
for (v >>= 1; v; v >>= 1)
{
r <<= 1;
r |= v & 1;
s--;
}
r <<= s;
return r;
}
static inline u8 u8_bit_reverse(u8 v)
{
u8 r = v;
int s = 7;
for (v >>= 1; v; v >>= 1)
{
r <<= 1;
r |= v & 1;
s--;
}
r <<= s;
return r;
}
