What is Marie in computer architecture?
MARIE, a Machine Architecture that is Really Intuitive and Easy, is a simple architecture consisting of memory (to store programs and data) and a CPU (consisting of an ALU and several registers). It has all the functional components necessary to be a real working computer.
How do you call a subroutine in Marie?
MARIE provides a way to call these subroutines by using the JnS instruction, and normal program execution can be resumed once the subroutine exits by using the JumpI instruction. The JnS instruction stores the address of the next instruction after it was called.
How many opcodes can Marie support?
Memory addresses range from 0 through 4,095 inclusive. 5. Sixteen–bit instructions, with 4–bit opcodes and 12–bit optional addresses. This implies a maximum of 24 = 16 opcodes.
How big can a memory address Marie work with?
The MARIE Architecture it supports 212 words of memory. This is 4K words, addressed 0 to 4,095 inclusive. It might be said to have 8 KB of memory, but it does not support byte addressing.
