In this part of the VHDL CPLD course, a ring counter is written in VHDL and then implemented on a CPLD. This tutorial is also used to demonstrate the use of the VHDL ror and rol operators. Although not used in a ring counter, the related VHDL srl and sll operators which are also related to shifting are also demonstrated. -as drjohnsmith and tsjorgensen say, "DON'T" use the VHDL operators (srl, sll, sra, sla) because: 1) they never worked properly (see and article) 2) they are no longer part of the VHDL language The library ieee.numeric_std has the shift_left and shift_right operators for signed and unsigned types.

A shift register has the capability of shifting the data stored in the register from left to right or right to left.

Please refer to the IEEE VHDL language reference manual for more information on predefined shift operations. Use only one type of shift operation. 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.
