How does pipelining improve CPU efficiency? What’s the potential effect on pipelining’s efficiency when executing a conditional BRANCH instruction? What techniques can be used to make pipelining more efficient when executing conditional BRANCH instructions?
What is the point of using cache memory if we already have volatile RAM (Random Access Memory)?Transistors are used in both random-access memory (RAM) and cache memory. Is it conceivable, if at all possible, to employ just one kind of memory to carry out all of a computer's functions?
The rationale behind the inclusion of cache memory in computer systems is not clear to me, given that transistors are utilised in the construction of both random access memory (RAM) and read-only memory (ROM).Temporary storage can be conceptualised as a transiently available form of RAM (random access memory). Can one envision a computing device that solely relies on a single type of memory?
6. Assume that two numbers: dividend and divisor are saved in memory address M1 and M2 respectively. Quotient and remainder should be saved in R1 and R2 respectively. Write assembly language instructions and then list microoperations for each instruction and list the control signals required to be activated for each microoperation. MBR is used as buffer for any register to register transfer operation.

. Consider a system that has multiple processors where eachprocessor has its own cache, but main memory is shared among allprocessors.1. a) Which cache write policy would you use?2. b) The cache coherency problem. With regard to the systemjust described, what problems are caused if a processor has acopy of memory block A in its cache and a second processor,also having a copy of A in its cache, then updates mainmemory block A? Can you think of a way (perhaps morethan one) of preventing this situation, or lessening itseffects?
Why is it necessary for us to have cache memory when we already have RAM (Random Access Memory), which is a kind of memory that is believed to be volatile?Random access memory, also known as cache memory, and random access memory (RAM) are both types of memory that utilise an electrical component called a transistor. Is it really conceivable to employ just one kind of memory to carry out all of a computer's operations, and if so, is it even possible?
It's easy to wonder why we need cache memory since we already have RAM (Random Access Memory) as a volatile memory, given that both employ transistors as their fundamental structural component. This is because both cache memory and RAM rely heavily on transistors for their operation. Can a single form of memory be used for all of the computer's tasks, or are many types of memory necessary?
Problem: Consider a processor with FOUR general purpose registers only. i. Draw block diagram of the processor with two internal buses. ii. List ALL operations ALU is able to perform iii. Write all control signals to perform all operations including those listed in part (ii) iv. Write control sequence for adding the content of the memory location whose address is at memory location pointed by immediate number NUM to register R1. Assume the number NUM is provided by control unit. v. List factors which contribute to generate control signals with at least on example of each factor
Assume two secondary memory processes exist. In light of phase 1, one priority is higher than the other. Only one process can fit in main memory. How does the CPU work on it? Can you explain the whole CPU mechanism?
Assume that the operation times of one add instruction for the major functional units are 325 ps for memory access, 185 ps for ALU operations and 125 ps for register file read/writes. Please fill the table first and perform the following a )What is the total cycle in single-cycle implementation? b )What is the total cycle in pipelining implementation? c) What is the total cycle in pipelining implementation if there are 5 million add instructions? d) What is the total cycle in pipelining implementation for 5 million add instructions, if the stages are balanced? e)What is the speed up of pipelining implementation over single-cycle implementation?
Why do we need cache memory when we already have RAM (Random Access Memory), which is a kind of memory that is believed to be volatile?Random access memory, also known as cache memory, and RAM both employ the same kind of electrical components known as transistors. If it is even conceivable to do so, would it be possible to employ only one kind of memory to carry out all of a computer's functions?
The topic of why we need cache memory when we already have RAM (Random Access Memory) as a volatile memory naturally arises given that both cache memory and RAM employ transistors as its fundamental structural component. This is because the main structural element of both RAM and cache memory are transistors. Is it feasible to use a single form of memory to serve all of the computer's varied needs, or are many types of memory necessary?
