An explanation in the comments is very good (also see the 2nd related link). Anytime the processor executes a SWI (software interrupt) instruction, it goes into SVC mode, which is privileged, and jumps to the SWI exception handler. Reciprocal inst., Math. Arm’s CPU instructions are reasonably atomic, with a very close correlation between the number of instructions and micro-ops. Both are 100% downward accessible and all full panels can be removed 0000005528 00000 n Each vector has 4 bytes, containing a branching instruction in one of the following forms: • B adr: Upon encountering a B instruction, the ARM processor will jump immediately to the address given by adr, and will resume execution from there.The adr in the branch instruction is an offset from the current value of the program counter (PC) register. These enable the processor to perform multiple operations with a single instruction. The novel part is the way the instruction set is structured allows for code generation without knowing what the implementation defined total vector length is. The first step in using these extensions is to provide the necessary data types.
