Bit order in a byte

WebNov 19, 2024 · No, Python supplies no way to reverse the bit order - but you don't need to. The article made you overly paranoid ;-) The endianness of byte order is normally invisible to software. If, e.g., you read a 2-byte short in C, the underlying hardware delivers a big-endian result regardless of the physical storage convention. WebThe order of allocation of bit-fields within a unit (high-order to low-order or low-order to high-order) is implementation-defined. The alignment of the addressable storage unit is unspecified. You cannot guarantee whether a bit field will 'span' an int boundary or not and you can't specify whether a bitfield starts at the low-end of the int or ...

WebJan 18, 2024 · A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively. Because bits are so small, you rarely work with information one bit at a time. Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like "h". WebMay 5, 2024 · With one of those functions you are looking at 0.7s extra to do that many bytes.

WebWhen the bit order of a byte must be changed, we commonly refer to this as reversing the bit sex. Color sex problems result when the value of the bits in a byte are the inverse of what we expect them to be. Inverting a bit (also called flipping or toggling a bit) is to change a bit to its opposite state. A 1 bit becomes a 0 and a 0 bit becomes a 1.

WebHelpful description: bitSwap1 reverses each bit with it's neighbor, so if we number the bits (of the first byte) as 87654321, then after calling bitSwap1 we would go from 8-7'6-5'4-3'2-1 to 7-8'5-6'3-4'1-2. bitSwap2 does the same but in neighboring pairs of two, so continuing we would go from 78-56'34-12 to 56-78'12-34.
