Purpose

The purpose of this assignment is to review the readings for chapter $5$ from the textbook, Invitation to Computer Science. The questions will have you explore Von Neumann's architecture.

Instructions

Answer the following questions:

What does W represent when talking about memory?

At minimum how many bits are needed in the MAR for each of the following memory sizes?

$256$ MB

$45$ KB

$98$ MB

$128$ KB

$2$ GB

$6$ GB

$16$ GB

$1$ TB

How many memory cells are contained in $16$ GB of memory?

What is a ROM? How is it different from RAM?

In $2$D memory that has $8$GB $(8*230$ bytes$),$

What are the dimensions?

How large would the MAR be$?$

How many bits are sent to each of the row and column decoders?

How many output lines would each of the decoders have?

Assume a $64-$bit MAR that is organized with $32$ bits for the row selector and $32$ bits for the column selector.

What is the maximum size of the memory unit on this machine? Put your answer in terms of XB where X represents one of the byte units like G is Giga.

What is the byte unit for $260?$

What are the dimensions of the memory $($in bytes$)$ assuming a square $2$D organization?
