Tīmeklis2024. gada 14. jūl. · Floating-point FJCVTZS instruction sets the PSTATE.Z flag if the result of the conversion, when converted back to a double-precision floating-point number, gives precisely the same value as the original. Other PSTATE flags are cleared by this instruction. And there are similar descriptions for the other instructions. FJCVTZS is "Floating-point Javascript Convert to Signed fixed-point, rounding toward Zero". It is supported in Arm v8.3-A chips and later. Which is odd, because you don't expect to see JavaScript so close to the bare metal.

Most of the arithmetic and logical instructions in the Thumb and Thumb-2 instruction sets take three arguments. The first is the destination register, the second is the first operand (also a register), and the third is the flexible second operand. (If the destination register is omitted, the first operand is used as the destination.)
Tīmeklis2024. gada 11. marts · 1 Answer. Sorted by: 1. ARM CPUs use a so called vector table. It's an area in memory that contains the start addresses of all exception handlers aka ISRs. So if the vector table starts at 0x08000000 and the Systick exception occurs, the CPU interrupts the current work and loads the Systick ISR start address into the …
