Using nibbles (4 bits variables) in windows C/C++
2009年5月14日 — bool anotherBool : 1; unsigned int highestNibble : 4; }; The : 4 indicates that entry should occupy 4 bits. You can use any number of bits you like. You can use any built in type you like. Typically you end up casting a pointer to your data to a Header * then doing something like: pHeader->lowestNibble = 5;
Python split byte into high & low nibbles - Stack Overflow
2017年3月20日 — If you wanted to get the high and low nibble of a byte. In other words split the 8-bits into 4-bits. Considering the data string is a string of bytes as hexadecimals, then you could simply do:
Reading/Writing Nibbles (without bit fields) in C/C++
2010年6月24日 — 6. You may want to put this inside macros. If you're updating an existing value, you need to clear the nibble in byte before orring in the new value. byte = (byte & ~0xF) | (nibble1 & 0xF), and similarly for the top nibble. There are a couple of mistakes in the above code - you need a ~ in front of the byte masks.
.net - How can you nibble (nybble) bytes in C#? - Stack Overflow
Output: 2 bytes, each storing a nibble, meaning the 4 leftmost bits (aka high nibble) are 0000 while the 4 rightmost bits (low nibble) contain the separated nibble. byte x = 0x12; //hexadecimal notation for decimal 18 or binary 0001 0010 byte highNibble = (byte)(x >> 4 & 0xF); // = 0000 0001 byte lowNibble = (byte)(x & 0xF); // = 0000 0010
c - how to replace given nibbles with another set of nibbles in an ...
2016年12月23日 — Nibble has 4 bits, and according to your indexing scheme, the zeroth nibble is represented by least significant bits at positions 0-3, the first nibble is represented by least significant bits at positions 4-7, and so on. Simply shift the values the necessary amount. This will set the nibble at position set by the variable index:

2022年12月14日 — I'd like to move a nibble from Accumulator to upper nibble of P1. For now, I set the nibble bit by bit MOV ...
binary - How many bits are there in a nibble? - Stack Overflow
2016年9月20日 — A nibble has 4 bits (although it doesn't have to). That also means that when you view a byte's value in hex-notation, one hex digit corresponds to one nibble. That's one reason why going from hex to binary is much easier than from …
c# - converting a nibble to ist ascii value - Stack Overflow
2016年8月6日 — I need a solution for converting each nibble of a byte to its ASCII equivalent. So given: varA = 0xab; char varB = ASCii value of the upper nibble of 0xab 'a' (61) char varC = ASCii value of the lower nibble of 0xab 'b' (62) thanks ahead of …
Toggle nibbles in a 16 bit register (8086) - Stack Overflow
2020年5月28日 — 6. I'd strongly suggest reading the manuals for these processors if you're going to be writing any assembly for them. This can be done in a single instruction: XOR AX, 0xF00F. Inverting bits is easily done using an Exclusive or with 1 bits. By performing an exclusive or where the upper and lower nibbles of a 16-bit word are set, the bits in ...
