Vector table It is a table of addresses that the ARM core branches to when an exception is raised and there is always branching instructions that direct the core to the ISR. An entire array of integers or floating point numbers is processed in a single operation, eliminating the loop control mechanism typically found in processing arrays. After those vector are created, I measured performance for 100000 getDiff for those vectors and then 100000 getDiff2. Anytime the processor executes a SWI (software interrupt) instruction, it goes into SVC mode, which is privileged, and jumps to the SWI exception handler. You may need to rearrange the elements in your vectors so that subsequent arithmetic can add the correct parts together, or perhaps the data passed to your function is in a strange format, and must be reordered before your speedy SIMD code can handle it. This new book is the ideal gateway into Arm’s Helium technology, the M-Profile Vector Extension for the Arm Cortex-M processor series. For this reason, SVE leaves the vector length as an implementation choice (from 128 to 2048 bits, in increments of 128 bits).
