Suppose we enhance a computer to make all multiplication instructions run two times faster. If the execution time of some benchmark before enhancement is 1205ec, what will the speedup be if 805ec before improvement is spent executing multiplication instructions? (the answer is a numerical value only)

LI is the fastest type of cache memory built into a computer, faster even than DDR4 SDRAM memory. True or False?
A processor that can decode encrypted data and system instructions, and then execute the instructions on the decoded data and system instructions, has been suggested. Encryption will then be performed by the CPU. Using a CPU this way has what advantages? Is there a need for a certain CPU architecture?
Q: A digital computer has a memory unit of 64k * 16 and a cache memory of 1k words. The cache uses direct mapping with a block size of 4 words. i) How many bits are there in the tag, index, block & words fields of the address formats. ii) How many bits are there in each word of cache? iii) How many blocks can the cache accommodate?
Alert dont submit AI generated answer. Consider the following string of memory accesses. All of these access will miss, thus the hit rate will be zero.li t0, 0x1000sw t1, 0(t0) # 1sw t1, 0x10(t0) # 2sw t1, 0x20(t0) # 3sw t1, 0x30(t0) # 4sw t1, 0x40(t0) # 5What is the smallest offset greater than 0x10 that you can change #3 to that creates a conflict miss (specifically, evicting the data that was placed in the cache by instruction #2) in a 32-entry 4-word direct-mapped cache? Answer with the leading "0x".

Consider a demand-paging system with the following time-measured utilizations: CPU utilization 20% Paging disk 97.7% Other I/O devices 5% For each of the following, say whether it will (or is likely to) improve CPU utilization. Explain your answers. Install a faster CPU Install a bigger paging disk. Increase the degree of multiprogramming. Decrease the degree of multiprogramming. Install more main memory. Install a faster hard disk or multiple controllers with multiple hard disks. Add prepaging to the page fetch algorithms. Increase the page size.
Unlike a byte that is always 8 bits, word size can vary from machine to machine. Let's say we have a 16-bit system (word size is 2 bytes) and a memory unit that has 10 address lines. Because there are 10 address bits, we can have 210 unique addresses, hence 1024 addresses. If we are working with something word-addressable, that means each word has a unique address, and we canstore 1024 words. The memory size is 1 kiloword, or equivalently, 2kilobytes because each word is 2 bytes long. The address of the first word is 0, the second word is 1, the third word is 2, and the last word is 1023.Now, with 4 address lines and a word size of 4 bits, what is the address of the last word?
How would it be advantageous to prioritize the I/O queue above the process execution queue? What will happen if the I/O is interrupted is anyone's guess. Indications are conflicting as to how this could effect the maximum burst rate of the CPU. I'm confused as to the nature of your question.
Computer Science 9. In a paging system , the logical address is formed of 20 bits. the most significant 8 bits denote the page number, the least significant 12 bits denote the offset. Memory size is 256K bits. a. What is the page size (in bits)? b. What is the maximum number of pages per process? c. How many frames does this system have? d . Give the structure of the page table of a process executing in this system. Assume 2 bits are reserved for attributes. e. How many bits are required for each page table entry? f. If physical memory is upgraded to 1024 K bits, how will your answer to c and e change?
Suppose a computer system has 20K pages in the main memory with each page size of 4K bytes, with a total memory of 80M bytes, how many entries are there in the inverted page table? a 20,480 b 4,096 c 4000 d 40,000 e None of the above
How can we stop a CPU from squandering time by forcing it to multitask too much? What happens to our ability to put this plan into action if we can't get our hands on those funds? Give an example of the kind of results you may anticipate.
This was previously asked and answered, but I need it in a format similar to what is depicted in the image attached, but with 6 stage instead of 4 stage. R1 = X + 1Y = R1 + R2R1 = R2 + X Complete the following: Lay the instructions out as they would be fed through a 6-stage CPU pipeline not accounting for any hazards. S1: Fetch instruction, S2: Decode opcode, S3: Calc effective address of operands, S4: Fetch operands, S5: Execute instruction, S6: Store result Identify any hazards present "Fix" the pipeline process to remove the hazards
