VHDL Operators Highest precedence first, left to right within same precedence group, use parenthesis to control order. Unary operators take an operand on the right. "result same" means the result is the same as the right operand. Binary operators take an operand on the left and right. "resul...
There are many ways to create a shift register in VHDL, though not all of them are equal. You can dramatically reduce the number of consumed resources by choosing the right shift register implementation for your needs and FPGA architecture. A shift register implements a FIFO of fixed length. ...
