What is assembler programming language like?
STM always saves lower numbered registers in memory before higher numbered ones. Thus if the correct ordering on the stack is to be obtained, register str2 must be lower than str1, which must be lower than result.
Of course, if this weren't true, correct ordering on the stack could still be achieved by pushing and pulling the registers one at a time. For most purposes, integer as opposed to floating point or 'real' numbers suffice, and we shall discuss their representation and operations on them in this section.
Integers come in varying widths. As the ARM is a bit machine, and the group one instructions operate on bit operands, the most convenient size is obviously bits. Unsigned integers give a corresponding range of 0 to 4,, When stored in memory, integers are usually placed on word boundaries.
This enables them to be loaded and stored in a single operation. Non word-aligned integer require two LDRs or STRs to move them in and out of the processor, in addition to some masking operations to 'join up the bits'. It is somewhat wasteful of memory to use four bytes to store quantities which need only one or two bytes.

We have already seen that characters use single bytes to hold an eight-bit ASCII code, and string lengths of up to characters may be stored in a single byte. There may be occasions, though, when you want to store a signed number in a single byte, i. Now LDRB performs a zero-extension on the byte, i.
This means that when loaded, a signed byte will have its range changed to To sign extend a byte loaded from memory, preserving its signed range, this sequence may be used: The arithmetic shift right then moves the byte back again, extending the sign as it does so.
After this, normal bit ARM instructions may be performed on the word.
If you are sceptical about this technique giving the correct signed result, consider eight-bit and bit two's complement representation of numbers.
If you examine a negative number, zero and a positive number, you will see that in all cases, bit 7 of the eight-bit version is the same as bits The store operation doesn't need any special attention: STRB will just store bits To load an unsigned bit operand from an byte-aligned address use: To store a sixteen-bit quantity at an arbitrary byte position also requires three instructions: The number can then be restored if necessary using: The group one instructions cover a good set of them, but an obvious omission is division.• Accessing an array element requires its displacement or offset relative to the start of the array in bytes S.
Arrays (cont’d) • In assembly language. as the assembly language programmer.
signed integer)» Index range (0 to 9 in C) • You get very little help in assembly language! S. Dandamudi. This program needs to enter the length of the entering array, followed by the array to be sorted.
The entered integers are stored in the array A. Logic: Here, to sort the data in ascending order, the first element A is compared with all the other elements till the end of the array.
Bubble Sorting program in assembly language on emulator Steps: 1- Declare an Array. 2- Set all elements to 0. 3- Take 10 inputs in the array.
4- Start a loop of 10 itteration. How do I to write a Java program to sort an array in ascending order? How can I rearrange the integer in a Java array in descending order? How do I sort a series of number ascending or descending order in assembly language ?

The end result is that the two first elements 3,2 or the original array are now in correct order respect to each other, 2, 3.
The whole array now looks like 2,3,1. How do I to write a Java program to sort an array in ascending order?
