1) Describe the von-Neumann Architecture and how it differs to the HarvardArchitecture. 2) On an interrupt the PIC 18F saves a copy of the PC register, the W register and the Status register. Describe these three registers, what do they hold and when do we use them? 3)What are the differences between analogue signals and digital signals? What are threshold voltages and why are they important?
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...
In a von Neumann architecture, groups of bits have no intrinsic meanings by themselves. What a bit pattern represents depends entirely on how it is used. Consider the following bit patterns expressed in hexadecimal notation. 8D28000C16 1) What decimal number does the bit pattern represent if it is an integer? 2) What decimal number does the bit pattern represent if it is an unsigned integer? 3) If the bit pattern is in an instruction register, what MIPS instruction will be...

This question is from Computer architecture. Please show steps and add comments so its easy to understand. Translate the high-level language code below into assembly instructions. The variables A, B, C, D, E and F are located in the memory and can be accessed by their label (e.g., LOAD R1, A will load A from the memory into R1). Minimize the number of instructions in the assembly code that you write. F = (A-B)*(C+D)/(E-D) a) Write the code for an...
