-



Control Memory

In a micro-program control, the control variables that initiate micro-operations are stored in memory called control memory.

•The control memory is a ROM, since the control sequence is permanent and needs no alteration.


Micro instructions

The word stored in the control memory are micro-instructions.

Each micro-instruction specifies one or more micro-operations for the components in the system.

We can start learning basics of Computer Organisation & Architecture  .  Understand the difference between computer architecture & organisation first . BASIC OPERATIONAL CONCEPTS  We can discuss about various operations used for transferring and manipulating data BUS STRUCTURE We can consider definition of BUS also about way of transferring data through Bus . MEMORY LOCATIONS & ADDRESSING Understand the basics of System Memory ,way of storing data in memory.  W can discuss here about memory addresses and about Byte addressable memory .At the end we will get the idea about memory size specification and how to calculate the address of memory bytes . INSTRUCTION EXECUTION &STRAIGHT LINE SEQUENCING Understand what an instruction is ,then learn about how to complete the execution of a program which is present in main memory of the system by executing set of instructions one after another . Here consider , two situations of instruction execution ,sequential execution and
