Question
A branch instruction changes thc flow of a program by changing the program counter (PC). 2. Rcgistcrs arc storagc locations within the CPU itsclif 3. A clock is a signal within a computer which tells the computer the time of day. 1. MARIE has a common bus schcmc, which means a number of cntitics sharc the bus. 5. The fastest form of memory is typically the cheapes 6. A 4Mx 16 memory chipcan store 4 x 10 16-bit words. 7. The micr)-controller on the Arduino ?NO is 1 he almega325 8. Tr MARIE is given the instruction LDAD Xe value of the variable X is loaded nto the AC -i. 9. A TabVTEW program consists of a block diagram and a front panel. 10. Programs which are interprcted will tend to cxccutc faster than those which are compilcd 11. The Event Structure in LabVIEW is a type of intcrrupt 12. Events which altcr the nomal low of program cexccution arc called intcrrupts. 13. The term endian refcrs to the order in which a computer storcs multi-byte data 14. The Amega328P is a 8 TBit mirco-controller 15. The code sippet DDRBI-1Explanation / Answer
1.) True A branch instruction is basically conditional instruction which makes a decision whichinstruction will be next executed and updates the PC accordingly.
2.)True Registers are smallest memory unit inside CPU.
3.)True. Computers have a "real-time clock" that is a special hardware device containing a quartz crystal on the motherboard that maintains the time. The system can refer to clock to know the time of day.
4.)True. MARIE has common bus where number of input/output operations takes place.
5.)False. The fastest form of memory like registers and cache in CPU is the most expensive. However, hard disks are not that expensive.
6.) True, 4M X 16 means it has 4 CHIP DEPTH IN MILLIONS OF LOCATIONS and 16 BITS CHIP WIDTH. Therefore it has four million 16 bit words.
7.) False. It is Atmega 328 rather atmega 325-D
8.) True. Load x by default means move x to acc.
9.) True. A labview consist of two major components Block diagram and front pannel.
10.) True. As in the interpreted programs, a block of code is executed togather, however, in compiled, each instruction is executed step by step.
11.) True. As event structures are used to handle interrupt-driven tasks such as UI interaction.
12.)True. Interrupts and signals are mechanisms that can alter the flow of control as a response to some external stimulus or event.
13.)True. Big-endian and little-endian are terms to describe the order in which a sequence of bytes are stored in computer memory.
14.)True. Atmega 328 p is high-performance Microchip picoPower 8-bit AVR RISC-based microcontroller .
15.)True. As PINB5 is nothing but pin 19 on 28 pin dip package.
