ARM Assembly Programming: Character Frequency Count

It involves writing a program in the ARM assembly language to count and display how often each character occurs in a string. It should design and implement frequency count. the code should process the hard-coded poem string: My hearts in the Highlands, my heart is not here, My hearts in the Highlands, a-chasing the deer; Chasing the wild-deer, and following the roe, My hearts in the Highlands, wherever I go.

The program should run like this

$ ./freq

0000000001

0000000032

0000000003

0000000006

0000000002

0000000001

0000000001

0000000001

0000000003

0000000001

0000000003

0000000011

0000000001

0000000007

0000000020

0000000001 0000000007

0000000017

0000000011

0000000006

0000000001

0000000011

0000000005

0000000010

0000000009

0000000011

0000000001

0000000003

0000000004

(a) Frequency table Parse the string character-by-character and increment the counters in the frequency table.

(b) Powers of 10 table Compute 10N for N from 0 to 9, storing the values in the powers ten memory locations (in the ten array).

(c) Convert counts to ASCII Convert the frequency counts to ASCII character values.

(d) Print the frequency table Display the count for each character in the format:

e.g. 0000000017 h
