Create a square wave of 440 hz in arm assembly language.
Create a square wave of 75% duty cycle on bit4 of port 2 by writing an assembly language programi ior 8051 microcontroller. Also, determine the frequency of the square wave if the delay routine given in problem 2 is used in this program. 5. 20 pts. Create a square wave of 75% duty cycle on bit4 of port 2 by writing an assembly language programi ior 8051 microcontroller. Also, determine the frequency of the square wave if the delay routine...
Write a program which produces a constant-amplitude square wave with a frequency of 440Hz (440 cycles per second). Using the init function, the output is configured to use signed 16-bit values for the signal, so a value of 0x8000 represents the “bottom” of the signal range, 0x0 represents the “middle” and 0x7FFF is the “top”. The output sample rate (the rate at which these 16-bit values come out) is 48kHz. This is all the info you need to put the...
Write an ARM assembly language program for Heap Sort.
In a 440 Hz sound wave the pressure in the compressions and rarefaction is about 1% higher and lower, respectively, than the pressure in the absence of sound. The sound is a) too soft to be heard b) about as loud as normal conversation c) deafeningly loud
Question 2 ARM Assembly Language (25 marks) An ARM instruction set summary is provided at the end of this paper. (5 marks) Explain the difference between eor and eors instruction. Use an example to show why both forms are useful. а. b. (5 marks) Explain using an example what the "Idr r3, [r7,#4]" instruction does. c. (10 marks) The following is the assembly language generated by a C compile type mystery, %function mystery: args 0, pretend = 0, frame =...
Language: ARM assembly Need help writing a program that takes user input as a string and outputs the string with all the vowels replaced with "x". For example, the string "Robot" should output ""Rxbxt"
Write ARM assembly language instructions to change the value of r0 as follows: • set the most significant byte of r0 to one’s (i.e., 0xFF) if the least significant byte of r1 is less than 90. • complement the least significant byte of r0 if r1 is odd.
ARM assembly language Write a program "fibonacci.s" that computes the Nth Fibonacci number where N is not so large that overflow of integer arithmetic is a concern. When your assembly language program is called it should expect the value of N to be passed using register r0 and your program should return the Nth Fibonacci number in register r0. Please include comments as well. Do not just use the output generated by gcc -S
Design a digital sine wave oscillator with f= 440 Hz, Sample rate = 5 kHz. Can the amplitude be adjusted without multiplication?
Write a program in ARM assembly language that copies each element of array A to consecutive fourth elements of array B, i.e., A[0] to B[0], A[1] to B[3], A[2] to B[7], etc. The array A is 12 elements long, and each element is a number that is 32 bits (1 word) wide. Assume the base address of array A is in register R2, and the base address of array B is in R3.
