What does the Accumulator do?
Consider where the CPU keeps its working results.
What does the Program Counter (PC) do?
Which register deals with the sequence of execution?
True or False: The Accumulator is responsible for holding the instructions ready for execution.
Which register is for computation results?
A CPU pulls an instruction from address 0x300, which points to the opcode 0x1 and address 0x940. Describe the result of executing this instruction based on the accumulator behavior.
What does the opcode signify in terms of operations?
If the PC is set to 0x300, and after one full execution of the instruction fetch and execute cycle, what would be the value of the PC if instruction length is 1 in hexadecimal?
Consider how the PC operates with instruction flow.
