What assembly language does ARM use?

The ARM architecture, like most 32-bit architectures, is well-suited to a using a C or C++ compiler. The majority of control code is written using high-level programming languages like C and C++ instead of assembly language.

What is the purpose of the proto directive?

This can be a useful way to verify that a program is working correctly. This PROTO directive also specifies the parameters and types of a given function.

What is the symbol used for representing comments in a typical ARM based instruction?

Since we’ll be assembling with the GNU assembler in the next article, we need to use the @ symbol to represent a comment. Hopefully this article gives you a foundational understanding of the basic instructions used to program an ARM core.

What is ARM programming?

ARM (stylised in lowercase as arm, previously an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments.

What is the purpose of invoke directive in assembly language?

The INVOKE directive is a powerful replacement for Intel’s CALL instruction that lets you pass multiple arguments. The PROC directive declares a procedure with an optional list of named parameters. type must either be one of the standard ASM types (BYTE, SBYTE, WORD, etc.), or it can be a pointer to one of these types.

What is Proto in assembly language?

The prototype definition basically tells the assembler how many parameters the respective function expects on the stack. In your case the API expects one 32bit parameter to be on the stack, which is reflected by the prototype like this: QueryPerformanceCounter PROTO :DWORD.

What is the processor used by ARM7 *?

What is the processor used by ARM7? Explanation: ARM7 is a group 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use.

What are labels in assembly language?

A label in a programming language is a sequence of characters that identifies a location within source code. In assembly language labels can be used anywhere an address can (for example, as the operand of a JMP or MOV instruction).

What type of assembly language is used in cs216?

The one we will use in CS216 is the Microsoft Macro Assembler (MASM) assembler. MASM uses the standard Intel syntax for writing x86 assembly code. The full x86 instruction set is large and complex (Intel’s x86 instruction set manuals comprise over 2900 pages), and we do not cover it all in this guide.

What is the best assembly language for writing x86 machine code?

There are several different assembly languages for generating x86 machine code. The one we will use in CS216 is the Microsoft Macro Assembler (MASM) assembler. MASM uses the standard Intel syntax for writing x86 assembly code.

How to declare static data regions in x86 assembly language?

When referring to registers in assembly language, the names are not case-sensitive. For example, the names EAX and eax refer to the same register. You can declare static data regions (analogous to global variables) in x86 assembly using special assembler directives for this purpose. Data declarations should be preceded by the .DATA directive.

What is an array in x86 assembly language?

Unlike in high level languages where arrays can have many dimensions and are accessed by indices, arrays in x86 assembly language are simply a number of cells located contiguously in memory. An array can be declared by just listing the values, as in the first example below.
