2.2.3. VHDL Data Types and Operators

Try these first

1. 1.

   What data type would you use to represent a binary value?

   Hint

   Think of digital signals.

2. 2.

   Which operator would you use to add two INTEGER values?

   Hint

   It's a basic arithmetic operation.

3. 3.

   Which of the following is NOT a VHDL data type?

   • BIT
   • FLOAT
   • INTEGER
   • BOOLEAN

   Hint

   Recall which data types are mentioned in VHDL.

4. 4.

   True or False: UNSIGNED can represent negative integers.

   • True
   • False

   Hint

   Think about the definition of UNSIGNED.

5. 5.

   Create a VHDL expression that evaluates if a BIT signal is high and an INTEGER signal is even using the appropriate operators.

   Hint

   Combine logical and relational checks in your expression.

6. 6.

   In a loop, calculate the sum of INTEGER numbers from 1 to 10 and print if each number is odd or even.

   Hint

   Utilize arithmetic and modulus operations in your loop logic.
