Bit-Level Operations
In a real DSP hardware system, not all operations can be expressed mathematically. Often a signal must be accessed
by its individual bits. System Generator supports a set of bit-level operations that allow the reinterpret, combining,
conversion and extraction of the individual bits of a signal. This can be used to pad, unpad and slice off the bits of
a signal with a high degree of control. These blocks do not use any hardware resources
