I'm hooked on bitwise for a new security paradigm I'm creating called VMAC. Variable Matrix Access Control. I want to do logical implication on to bit strings. (1) Before I reinvent the wheel, is there an established shortcut to emulate '->' (logical implication) using AND and OR and NOT or other basic SQL binary operators?
(2) XNOR believe it or not would allow me to cut '->' emulation down to four OPS: NOT, XOR, OR, AND. But it is not widely available. Any known shortcuts to XNOR? I was thinking of something like AND operation on operands plus NOTted operands off the top of my head.
Just trying to avoid echoeureka (reinventing the wheel).
Any comments (3) on efficiency achieved by implementation of bitwise data structures 0n 64-bit platform? Speed on multi-threaded apps using concurrent threads operating on word-size segments of larger data object?
(Sorry, I'm not a computer scientist)
