I'm dealing with some performance critical code-- a function which is called > 10^10 times in a typical execution. I've noticed that author used a lot of bit shifting instructions (foo >> 5) * (bar >> ...

Signal processing and communications algorithms frequently make use of dynamic bit rotates or shifts. Utilizing merged trees improves performance and reduces routing congestion using fewer resources.

The NPIC6C595 is a low power 8-bit shift register having a storage register and open-drain outputs. This shift register is a serial-in/serial or parallel-out device. It has low RDS(on) and has eight ...
