Start the simulator as directed.This simulator supports 5-valued logic.Procedure to perform the experiment:CPU Design What is the advantage of multiple-bus architecture rather than using single-bus architecture?.What are the main components of any general purpose computer?.What is the maximum memory address space that the processor can access directly if it is connected to a 16-bit memory address?.In a computer, the larger RAM increases the speed, because it reduces.The technique which repeatedly uses the same block of internal storage during different stage of problem is called.During read operation what is fetched by the CPU?.What is the advantage of memory interfacing?Įffective speed of the memory is increased.A single bus structure is found in generally.How many units in a single bus structure can communicate at a time?.What are the possible states that define the instruction execution?.What general catagories of functions are specified by computer instructions?.The refreshing rate of dynamic RAMs is approximately once in.General purpose internal registers are also called.The minimum time delay required between initiation of two successive memory operations is called The program controller of digital computer works.For halting, it uses self loop, no other halt instruction is provided. The working memory should contain the programm and data in binary format. In this experiment, no I/O module has been included for the purpose of simplicity. Mem denotes the contents of memory address a.The single instruction which this CPU supports is SBN (subtract and branch if negative). A working memory has been provided to check the working principle of the CPU. This experiment provides a single instruction CPU with built-in controller. After fetching an instruction, processor execute the instruction by doing some processing on the data which may involve arithmetic and logic unit (ALU), specified by the instruction, then processor writes back the result (if any) to the memory.The basic instruction cycle is shown in the following figure: The fetched instruction is fetched into a register called instruction register (IR).

Unless told otherwise the processor always increments PC after each instruction fetch so that the next instruction is fetched in sequence. A register called program counter (PC) holds the address of the next instruction. Processing required for a single instruction is called an instruction cycle which consists instruction fetch and instruction execute. The basic function of a computer is to execute a program which consists of a set of instructions stored in the memory.

At the top level a computer system can be described as followes: These modules are interconnected in a specific manner to achieve the basic functionality of a computer i.e. At the top level a computer consists of a CPU (central processing unit), memory, I/O components, with one or more modules of each type.
