Microprocessors(ECE303)-Lab-Viva Viva is 5 Marks . 1/2 mark for each question. *Required Enter your Name * Asmita Consider the following registers: 1. Accumulator and flag register 2. B and C * register 3. D and E register 4. H and L register . Which of these 8-bit registers of 8085 microprocessor can be paired together to make a 16-bit register? 1 ,3 and 4 2 ,3 and 4 1, 2 and 3 1, 2 and 4 Consider the following I) Sign flag II) Trap flag III) Parity flag IV) Auxiliary carry flag . Which one of the above flags is/are present in 8085 microprocessor? * (I) only (I) & (II) (II) & (III) (I) ,(III) & (IV) In 8085 name of the 16 bit registers is * Stack pointer Program counter both A and B none of these Which instruction is required to rotate the content of accumulator one bit right * along with carry? RLC RAL RRC RAR Temporary registers in 8085 are * B and C D and E H and L W and Z Register pair used to indicate memory * B and C D and E H and L W and Z In 8085, the 16-bit address bus, can address upto? * 16KB 32KB 64KB 128KB It is also a 16-bit register works like stack, which is always incremented/decremented by 2 during push & pop operations. * Stack pointer Temporary register Flag register Program counter For a microprocessor to execute a program, the CPU has to do the following operations: * Fetch the opcode Read a memory location for the data. Perform the required operation All of the above. The speed of a microprocessor is usually measured by the * Microprocessor’s throughput. Speed with which it performs I/P and O/P operations. Time required to execute basic instruction. Time required to process a small operation. Get link Never submit passwords through Google Forms. This content is neither created nor endorsed by Google.
