WebJul 20, 2014 · 1. as an exercise problem in ARM assembly program, I had to convert a number x to its absolute value. now seeing the problem as a simple problem of removing the sign of the respective number, I used BIC instruction to clear the MSB sign bit. later on I found out that RSBMI instruction is present in ARM to compute the absolute value of any … WebARM Assembly Load/Store Load/Store Memory Types Almost all modern microprocessor have the ability to access two types of memory. The first type of memory is a non-volatile …

WebMar 27, 2013 · 2. The exact answer will depend on which microcontroller you are using. In general, if there are no operands, BEQ would be expected to branch if the Accumulator is 0. This is most likely on simple micros where the Accumulator is the primary register for … WebOperation. The BX instruction causes a branch to the address contained in Rm and exchanges the instruction set, if required: BX Rm derives the target instruction set from bit [0] of Rm: If bit [0] of Rm is 0, the processor changes to, or remains in, ARM state. If bit [0] of Rm is 1, the processor changes to, or remains in, Thumb state.
