In VHDL, there are two types of functions, pure and impure functions. SLA : (Shift Left Arithmetic) Example 1. result <= vect sla 1 output : vect = 1 0 X 1 Z result = 0 X 1 Z Z In SLA LSB bit is replicated. Example 2. result <= vect sla 2 output : vect = 1 0 X 1 Z result = X 1 Z Z Z In SLA LSB bit is replicated twice (ie.,no of shifts).
