Why do we need Registers?
If tcpu is cycle time of CPU which is the time taken by CPU to execute a well-defined micro-operation employing registers and tmem is memory cycle time which is the speed at which memory can be accessed by CPU then (tcpu/tmem) is in the range of 2 to 10 i.e. CPU is 2 - 10 times faster than memory. So CPU registersare the fastest temporary storage areas. So the instructions whose operands are stored in fast CPU registers can be executed fast in comparison to instructions whose operands are in main memory of a computer. Every instruction should designate the registers it will address. So a machine needs a large number of registers.

Von Neumann architecture was first majoranticipated structure for general-purpose computer. However before consideringmain components of von Neumann architecture let us first elabo
Method : The master from which the copies will be taken is first prepared from a special non-absorbent glazed sheet of paper and special carbon paper which acts as the reproducing
Minimize the logic function Y(A, B, C, D) = ∑m(0,1,2,3,5,7,8,9,11,14). Use Karnaugh map. Draw logic circuit for the simplified function. Ans: In following figure (a) shows the
Simple instruction formats: RISC uses simple instruction formats. Usually only one or a few instruction formats are used. In these machines instruction length is fixed and alig
What is race around condition? Ans: Race Around Condition:- Jn Kn Q(n+1) output 0 1 0 1 0 0
A doubly linked list is like a linked list except that each node has a pointer both to the next node in the list and to the previous node in the list. There are also pointers to th
In a raw Itanium, a "Processor Abstraction Layer" (PAL) is integrated into the system. When it is booted the PAL is loaded into the CPU and gives a low-level interface that abstrac
Quadratic probing: In the above case when the first insertion is made the probability of latest element being inserted in a certain position is 1/n where n is the size of the a
There are two methods to update your BIOS chip: 1. Flash it (software method) 2. Program it with an EEPROM programmer. This is a hardware method. This is how we at BIOSMAN pr
