assume 64 bit x86 (“x64”) In a malloc() implementation with n bytes free, is it better to have a single free block of size n, or several smaller free blocks whose sizes add up to n? Why?
Below is a program block written in ARM Assembly. Since initially PC = 0x2000, Stack pointer sp = 0x400 (no data in the stack memory and shown next), what are the LR and SP values when PC = 0x2028 (when the corresponding row is executed)? A. LR = 0x2048,SP = 0x3F0 B. LR = 0x201C,SP = 0x3F4 C. LR = 0x202C,SP = 0x408 D. LR = 0x2008,SP = 0x3F8 E. LR = 0x201C,SP = 0x404
Considering the following contents of Stack Segment (SS) Register and Stack Pointer (SP) Register: SS = A5B0H, SP = 4DF0H (a) Calculate the values of Top of Stack (ToS) and Bottom of Stack (BoS)? (b) Consider the following operations on the stack: PUSH AX PUSH [CX] PUSH 10 POP [BX] POP AX What is the value of ToS after all these operations? Also, provide the value of ToS after each instruction.
What is the smallest unsigned value we must pass to the following function to trigger a stack overflow (assuming a stack size of 64 bytes and that we are compiling and running as the only task on an x86-64 system)? Give your answer in decimal. unsigned long rec(unsigned long x){ if(!x) return 17; return rec(x >> 1) << 1; }
Suppose a computer using direct mapped cache has 232 byte of byte-addressable main memory, and a cache of 1024 blocks, where each cache block contains 32 bytes. a) How many blocks of main memory are there? b) What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag, block, and offset fields? c) To which cache block will the memory address 0x000063FA map?
Write a service routine which resets all elements of an array that resides in memory location from A000 H to A0FF H with DS equal to 0000 H. The service routine address is CS:IP where CS is 2000 H and IP is 0100H. Assume the interrupt type that is called is 50 (x8086- nano)
write a subroutine (in assembly) for ARMcortex-A9 that 1. accepts a memory address A passed in register r0 2. Sum the words incrementing from address A, until the accumulating sum would be considered a negative number ( A is first address read). 3. Return the final value in r 0 . Should preserve state of system using the stack pointer (sp). If you are unable to write Assembly code to complete this problem, please use comments and/or pseudocode as much as possible to describe what should be done.
