2. Encode the following four TM4C Thumb-2 instructions using 16-bit instructions if possible: LDR R3,[R0] MOV R2,R3 STR R6, [SP, #0x08] RSB R11,R7,R7, LSL #2 Note: uVision may NOT give the 16-bit answer for encoding when you check.
What does the ADR instruction do in Arm Architecture. For example: ADR R0, R0, R1 please compare the ADR and the LDR instructions, and feel free to use your examples for any of the questions. Thank you very much.
1 For a given processor bound workload the frequencies of instructions move (MOV), floating add (FADD), and floating multiply (FMUL), and the corresponding instruction run times, for a given processor are: FADD 10 300 Others 50 160 MOV Instruction Frequency 30 Time [nanosec] 100 FMUL 10 600 What is the MIPS indicator of this processor? Faster memory chips reduce the MOV time by 50%, and all other times by 20%. What is now the value of the MIPS indicator? The...
