Exception and Interrupt Handling in ARM interrupts requiring fast response and low latency like for example data Undefined Instruction and SWI cannot occur Here is an example of a very simple SWI dispatch routine to give you a feel for how it works. At address &8 is a branch to this routine: .swi_handler STMFD sp!, {r12} LDR r12, [r14, #-4] ; load the SWI instruction BIC r12, r12, #&FF000000 ; keep only the SWI number CMP r12, #SWIcount ; SWI in range?

Example SWI 0x18; "ARM Exception Handling and SoftWare Interrupts SWI" is the

System Calls swi 0x420000. This is how you call the system on ARM. The instruction swi jumps to a predefined address, which in turn jumps to the system call handler. Operating Modes, System Calls and Interrupts show how system calls can be made and handled using the swi instruction, instruction set when compared to ARM.

SWI functions are called by executing the SWI instruction. When the ARM controller leaves this It generates different code instructions to call SWI functions. 3. The Instruction Set. It is very simple because it contains just one instruction, SWI, For example, when the ARM is executing a series of group one

ARM Assembler Workbook Penn State College of Engineering. ARM SWI instruction. The top-level SWI handler typically accesses the link register and loads the SWI instruction from memory, and therefore has to be written in assembly language. The individual routines that implement each SWI handler can be written in C if required., The most different area between GCC and IAR Embedded Workbench for ARM is Inline Assembler and such constructions EXAMPLE 2 -- Using SWI instruction..

    ARM Angel SWI Instruction Usage All Angel SWI operations use the following instruction: swi 0x123456 An example of using one of these SWI operations is shown below. The above are relevant parts from a minimal swi working example. Note that this only works for svc/swi instructions in arm mode not thumb nor thumb2, if you want to make a generic works in all modes, I recommend you dont bother with the svc immediate and instead pass something in a register.
