I am looking for the value in hex. in the destination register R1 and the updated flags, if necessary, after each operation. Each operation is independent. Not a code.

Problem A. On an ARMv7-M processor, assuming that [R1]-0x7F0E0C2D, [R21-0x2468ACE0, [R3-0x1 048B3C5, [N-bit-0, [Z-bit] 0, [C-bit] 1, [V-bit] -0, predict the 32-bit [RI] and all four condition flags in APSR after an ARM arithmetic/logical instruction is executed in EACH case. (These instructions are NOT executed one after the other one; instead, each instruction starts with the initial conditions given in the statement.) (a) ADCS RI, R3, ROR #0x18 (b) ADDW RI, R2, #0xF1 B (c) SUBS R1, R2, R3 (d) RSBS RI, R2,#0x12 SBCS RI, R3, LSL #12 (f) EORS RI, R2, R3, LSR #4 (g) BICS R1, R2, R3, RRX (h) ANDS RI, R2, ASR #28 (i) ORR R1, R2, R3 (j) ORN RI, R2, #0xB600B600 ( (e) 1-0x941 BC081 , [N-bit-1, [Z-bit-i, [C-bit] =
