- 8) The physical address is the actual location within the RAM. It is put on the address bus by the CPU to be decoded by the memory circuitry. If CS = 426FH and IP A436 H, determine the following: %3D a) Logical address, b) Offset address, c) Physical address, d) Lower range of the code segnment, and e) Upper range of the code segment.The memory unit of a computer has 1M words of 32 bits each. The computer has an instruction format with 4 fields: an opcode field; a mode field to specify 1 of 6 addressing modes; a register address field to specify one of 28 registers; and a memory address field. Assume an instruction is 32 bits long. Answer the following: a) How large must the mode field be? b) How large must the register field be? c) How large must the address field be? d) How large is the opcode field?(b) Describe the difference between the virtual memory and Round Robin.
- a) Each of the 4 processors in a shared memory multi-processor system is rated at 800 MIPS. A program contains a purely sequential part that accounts for 42% of the program’s execution time on a single processor. The remaining code can be partitioned into three independent parts (A, B, and C). Running on a single processor, part A accounts for 20% of the program’s execution time, part B accounts for 18% of the execution time, and part C accounts for 20% of the execution time. All four processors can be used to execute the program, but the sequential part must be completed before the remaining independent parts (A, B or C) can run in parallel. Compared to running on the single processor system, what is the speedup ratio provided by running the program on the 4-processor system? Express your answer to 3 decimal places (d.ddd). b) On a different SMP 4-processor system, each of the four cores has a separate L1 cache, but the 4 processors share a single L2 cache. This system executes a…the available space list of a computer memory is specified as follows: 9 start address block address in words 100 50 200 150 450 600 1200 400 determine the available space list after allocating the space for the stream of requests consisting of the following block sizes: 25,100,250,200,100,150 use i) first fit ii) best fit and iii) worst fit algorithmsFor each question, give the following three values for the last line of each code block following the execution of the entire block: 1. the memory address which that line writes to, 2. the value that is written to that address, and 3. the number of distinct memory reads required by that line. If you cannot determine the memory address from the information given, enter 0 for the address. When computing the number of memory reads, assume nothing about the value of registers prior to the execution of the last statement: count a read even if the previous line also read (or wrote) the location. Count the number of distinct memory locations read by that statement; that is, if the line reads a memory location multiple times, count it only once. Assume that memory accesses always succeed, i.e. that all memory addresses are accessible to the program. For example, for the following code block: int *foo (int *)0x1000; int *bar = (int *)0x1000; *foo = 1; *foo=foo + *bar + 1; you would answer…
- A computer employs RAM chips of 512 x 16 and ROM chips of 1024 x 8. The computer system needs 4K bytes of RAM and 2K bytes of ROM along with interface unit of 128 registers each. A memory mapped I/O configuration is used. The two higher order bits are assigned for RAM, ROM and interface as 00, 01 and 10 respectively. a) How many RAM and ROM chips are needed b) Design a memory-address map for the above systemUpload answer sheets A computer manufacturing company is involved in memory design. They need to develop a proper plan before entering into the production part. The objective is to design a memory based on five partitions of varied sizes. The sizes are as mentioned below: 100 KB, 200 KB, 300KB, 400KB and 500 KB. With these varied partition sizes available, the allocation should be made to four processes of sizes 357KB, 212KB, 426 KB and 468 KB. The three available allocation algorithms called First Fit, Best Fit and Worst Fit, perform the allocation of the processes.2. A memory location has a logical address where the segment address is the first four digits is your roll number and the offset address is the last four digits of your roll number. Find the physical address of the memory location. [example: if your roll number is 1234200516789, then the segment address is 1234h and the offset address is 6789h]
