VI - RAID 5 Hardware assist on PLB The block diagram figure 2 shows that a XOR and Not XOR function is attached directly to the PLB and computes the parity in each cycle when a new operand is entered ...

XOR (exclusive or) is a vital logical operation that’s used in various capacities in a lot, if not all, cryptographic algorithms. Figure 1 shows how this function works.

There is no software in the world that can execute an XOR function without having access to a physical XOR device. The current Section 112 (f) reads: (f)Element in Claim for a Combination.— ...

Logical functions. When studying logic, one must begin with the basic functions. Input values can be combined using the logical AND, OR, and exclusive OR (XOR) functions (Fig. 1 at right). Logic gates ...

XOR, or "exclusive OR," outputs true only when the inputs differ, and achieving this function typically requires a complex combination of logic gates. In traditional circuits, more than a dozen ...
