CPU Architecture

All the instructions that any particular CPU can use are known as the 

• Instruction set
• Keyword set
• Word set
• Character set

All data goes into and out of the CPU via the control unit

• True
• False

The Accumulator is a type of what?

• Register
• Buffer
• RAM
• Cache

Von Neumann processors have seperate areas of memory for data and the programs that use them

• True
• False

Von Neumann computers use two processors

• True
• False

Von Neumann processors fetch blocks of instructions, decodes them and then executes them. It has been designed like this because it is the most efficient way of executing a program

• True
• False

Instructions are fetched and decoded under the management of the ALU

• True
• False

Which of these is not a step in the FDE cycle?

• Instructions are fetched from main memory
• Instructions are decoded in the control unit
• The decoded instruction is executed
• The ALU decodes the instructions
