If 0 Times 38 and 0 Times 7D are considered as two 8 bits signed numbers, what will be carry flag (C), sign flag(N) and overflow flag(O) after an addition operation is operated on these two numbers? C = 1, N = 0, O = 1 C = 1, N = 1, O = 1 C = 0, N = 1, O = 1 C = 0, N = 1, O = 0 Which of the following statements on RISC and CISC is incorrect? RISC machines have simpler construction set, higher clock rate, more complex compiler and low development cost. CISC machines have dense code, simpler compiler, more powerful instruction set Both Intel Pentium and ARM processors are CISC processors. Most of the smart mobile phones today use RISC processors. Which of the following statements on ARM processors is incorrect? ARM is the industry\'s leading provider of 32 bit embedded microprocessors. ARM has three families, ie, Classic, Embedded and Application Cortex-M series belong to ARM embedded family. All the ARM instructions have fixed 8 bytes length Which of the following statements on ARM architecture and instruction set is incorrect The main attributes of ARM architecture are small implementation size, high performance and low power consumption The 32 bit ARM processors are based on RISC principle ARM architecture is only supported by ARM unique software development tools ARM has common instruction sets across all architecture variants Which of the following statements on ARM registers is correct? Z flag is the indicator of the sign of a signed number. Flag F in PSR register is used for the indication of overflow. R13, R14 and R15 are also named as SP, LR and PC ARM has 15 registers R1 ~ R15

Solution

Question 6: a) C=1, N=0, O=1

Question 7: c) Both intel pentium and ARM processors are cisc processors

Question 8: d) All the ARM instructions have fixed 8 bytes length

Question 9: d) ARM has common instruction sets across all architecture variants

Question 10: c) R13, R14, R15 are also named as SP, LR, PC
