Question 3: ARM Processor a) What is the number of bits in a general-purpose register (e.g., R1) of the ARM Cortex-M4 processor (CPU)? b) What is the number of bits in a memory address for the ARM processor architecture? c) What is the number of bits in an assembly instruction for the ARM Thumb-2 instruction set? d) Consider the memory map used with the TM4C123 microcontroller shown below. If the stack is in data memory, what is the initial address...
QUESTION 16 In the ARM Cortex MO core which register holds the memory address of the next instuction to be loaded from memory and usually increments by 2 when each instruction is executed? O a. Address register b.Instruction register C. Register bank d. Arithmetic and logic unit (ALU) Program counter ■ f. Instruction decoder ■ g. Control unit Z e.
The AVR provides a rich instruction set to support high-level languages. The AVR address- ing modes also simplify the access of complex data structures. The AVR has a version of the ADD instruction that includes the C flag as one of the source operands, which enables multiple- precision addition operation. The AVR also has a version of the SUB instruction that includes the C flag as one of source operands and hence is used to perform multiprecision subtraction operation. The...
Write a program in assembly language that loads register R2 with the word in memory location which is 10 bytes above the address in R0; and loads register R3 with the word in memory location which is 10 bytes below the address in R1. Your program must compare the two numbers in R2 and R3. If number in R2 is less than or equal to the number in R3 it must add the two numbers and save the result in...
4 pts Question 16 A simpler and more elegant approach is memory-mapped I/O because I/O devices and main memory share the: same memory space. same register same address space. Same Interface.
Consider a 32-bit hexadecimal number stored in memory as follows: Address Value 100 2A 101 C2 102 08 103 1B If the machine is big endian, what is the value stored at address 100-103 as an unsigned integer? If the machine is little endian, what is the value stored at address 100-103 as an unsigned integer?
Consider a virtual memory system with a 16-bit virtual address, a 10-bit physical address, and a 64-byte page size. The virtual address, 0x1235, is translated into a physical address using the page table below. VPN PPN Valid 44 02 1 45 05 1 46 08 0 47 --- 0 48 03 1 49 0A 1 4A --- 0 1. What is the hex VPN? (Enter as digits without 0x.) 2. What is the hex VPO? (Enter as digits without 0x.)...
