PER Aligned: a fixed number of bits if the integer type has a finite range and the size of the range is less than 65536; a variable number of octets otherwise; OER: 1, 2, or 4 octets (either signed or unsigned) if the integer type has a finite range that fits in that number of octets; a variable number of octets otherwise
Unlike the bitset in C++, the Java BitSet does not have a "size" state (it has an effectively infinite size, initialized with 0 bits); a bit can be set or tested at any index. In addition, there is a class EnumSet , which represents a Set of values of an enumerated type internally as a bit vector, as a safer alternative to bit fields.
There is no defined way to include or refer to such an external specification within a Protocol Buffers file. The officially supported implementation includes an ASCII serialization format, [ 6 ] but this format—though self-describing—loses the forward- and backward-compatibility behavior, and is thus not a good choice for applications ...

LZCNT is related to the Bit Scan Reverse (BSR) instruction, but sets the ZF (if the result is zero) and CF (if the source is zero) flags rather than setting the ZF (if the source is zero). Also, it produces a defined result (the source operand size in bits) if the source operand is zero.
Because bit-reversal permutations may be repeated multiple times as part of a calculation, it may be helpful to separate out the steps of the algorithm that calculate index data used to represent the permutation (for instance, by using the doubling and concatenation method) from the steps that use the results of this calculation to permute the ...
In the C++ Standard Library, the bit-array data structure bitset has a count() method that counts the number of bits that are set. In C++20 , a new header <bit> was added, containing functions std::popcount and std::has_single_bit , taking arguments of unsigned integer types.
When bytes are generated faster than the destination can use them and the producer is a software algorithm, the system pauses it with the same process synchronization techniques. When the producer supports flow control , the system only sends the ready signal when the consumer is ready for the next byte.
