Explore ARMv7 data processing instructions: data movement, arithmetic, logical, and compare operations in the ALU, with multiply in the MAC block and barrel shifter pre-processing to 32-bit results.
Learn the five logical instructions in ARM seven data processing—and, or, xor, bit clear, and orn—along with the instruction format, condition codes, s updates to CPSR, and flexible operands.
Explore move and compare data processing instructions in the arm instruction set, including data transfer via mu and mu negated, and flag updates with cmp, cmn, tst, and teq.
Explore ARM multiplication instructions MUL, MLA, UMULL, UMLAL, SMULL, and SMLAL, including 32-bit x 32-bit results, 64-bit long variants, and unsigned and signed operations with optional accumulate.
Explore conditional execution in ARM instructions, using eq and ne condition codes tested against z, c, v, n flags to execute or skip operations, boosting speed and code density.
Explore branch instructions in the arm instruction set, including b, bl, bx, and blx, and how arm thumb interworking uses lr and pc to switch states.
Explore ARM shift and rotate instructions—lsl, lsr, asl, asr, ror, rrx—driven by a barrel shifter boosting speed. See how logical and arithmetic shifts, carries, and rotates apply to data processing.
Explore arm single register load and store instructions, including ldr/str and ldm/stm, with sign and zero extension and indexing modes like pre/post indexing and endianness.
Learn to load multiple and store multiple (LDM and STM) copy 32-bit data blocks using increment and decrement suffixes and auto indexing with a base register for block transfers.
Demonstrates how stmfd, stmfa, stmed, stmea implement software stacks on ARM by using load/store multiple with stack oriented suffixes, enabling push and pop across ascending, descending, empty, and full stacks.
Explain how a software interrupt (SWI) triggers supervisor mode, stores state, and vectors to the SWI handler, detailing program counter and link register updates for returning to the main program.
In this course learner will learn basics of ARM7 instruction format along with all ARM instruction set.
All Arithmetic, Logical, MUL, Data Transfer Instructions are covered in this course along with detailed explanation.
These instructions are complex and perform multiple operations in one instruction.
ARM7 is a 32 bit processor architecture which is used to perform many operations.
In ARM7 load and store instructions are used to access memory.
In embedded system design assembly language programming is required. To write programs in assembly language its very important to learn and understand instruction sets.
Using this course learner will understand the ARM7 instructions and will be able to write assembly language programmes for ARM7.
ARM processors are available in three different Series A,R and M series. Most ARM processors support two or even three different instruction sets, while some (for example, the Cortex-M3 processor) do not in fact execute the original ARM instruction set. There are at least two instruction sets that ARM processors can use.
All registers inside ARM are 32 bit wide it means they can hold 32-bit data at a time and can process 32-bit data in one go. ARM7 in used in most of the embedded systems to process and control the system and data.
