 Exclusive disjunction - Encyclopedia.WorldSearch
In digital logic design, a two-input xor logic gate is often thought of as a programmable inverter, in that if one input is held at a logic '1', the output will be the inverse of the other input.
The xor operation is a more complex logical function than 'or' and 'and'.
Otherwise, if one input is held at logic '0', the output will always be the same as the other input.

 Xor swap algorithm
In computer programming, the xor swap is an algorithm which uses the exclusive disjunction (XOR) operation to swap the values of two variables without a temporary variable.
The following code in x86 assembly language uses the xor swap algorithm to swap the value in the AX register with the value in the BX register without using a temporary buffer.
XOR AX, BX XOR BX, AX XOR AX, BX However, all x86 microprocessors have an XCHG instruction which does the same work on its operands more efficiently than the above sequence of XORs.

 Self-repairing built-in self test for linked list memories - US Patent 6781898
Alternatively, the process of repairing defects in the linked list memories may be performed when the linked list memories are powered-on and may be an automated process that does not require input from an external source.
Also, the process may be applied to packet data linked list memories used in a network device, including a pointer memory and a packet data memory.
A process as recited in claim 1, wherein said linked list memories comprise packet data linked list memories used in a network device and said step of detecting faults in rows of other linked list memories comprises detecting faults in rows of the packet data linked list memories.

 Reversible Linked Lists
Linked lists and doubly linked lists are the first data structure anybody learns about formally.
The only trouble is, you need the list to be linked in the opposite order for the two uses, so you either have to construct a second copy pointing the other way, or use reversible lists.
This also makes it possible to pass a whole list around using only a pointer to the head: it's obvious which of the links to follow from the head, because you choose the one that isn't null.

 CocoaDev: DesignDoublyXORLinkedList
Lists can also be implemented with just one of these pointers, saving a pointer's worth of memory for every element in the list but losing the constant insertion, access and deletion to one end of the list.
The cost of a doubly-linked list is three pointers per element in the list: the previous and next pointers, and a pointer to the object stored at each entry.
Since the doubly-XOR-linked list is concerned with optimizing memory usage, there are other optimizations that go well with it.

Linux Journal has an article in the January 2005 issue that introduces a doubly linked list that is designed for memory efficiency.
Like most linked list implementations a NULL pointer indicates a non-existent node.
Using the example figure above, calculating the address of the B node from A looks like:

 Setting up A* Pathfinding - GameDev.Net Discussion Forums
If you need to keep two full lists and still maintain their pointers, then you might want to combine both node types into one class (if you're using C++) and build your lists to be of pointers to that class.
Posted - 10/6/2004 8:18:01 AM For the record lists are one of the worst ways to implement the queues in a A* algorithm, that said, it's is also one of the simplest ways to do it too, so since you don't really fully understand A* i guess it will do for now =).
Posted - 10/12/2004 8:11:13 PM For the sake of optimization, you might want to use a priority queue of pointers instead of a linked list and a bit/bool vector to signal the closed nodes.

Although a good understanding of how the linked lists works is helpful, the system calls do most of the hard work for you.
For setting up large symbol tables or other big data structures, linked lists (or binary trees) are the only realistic arrangement.
For the Z88 the pointers are three byte extended addresses, although note that if the most significant byte is zero this will not be taken to mean that the address is local, but rather as referring to bank 0 (ROM).

Normally, a dual-linked circular list would contain both previous and next pointer fields and the current position in the list would be identified by a single pointer.
Fortunately, that is equivalent to a parallel prefix XOR that can be computed using SWAR techniques in log time.
The well-known algorithm for conversion from Gray to binary is a linear sequence of XORs that makes it seem each bit must be dealt with separately.

The data pointer is generalized, so you have to make the appropriate conversions.
