Sample problem. Statement: Subtract the contents of memory location H from the memory location H and place the result in memory location H.

Statement: Add the bit number in memory locations H and H to the bit number in memory locations H and H. The most significant eight bits of the two numbers to be added are in memory locations H and H. Store the result in memory locations H and H with the most significant byte in memory location H. Program - 5. Statement: Add the contents of memory locations H and H and place the result in the memory locations Hand H.

Statement: Subtract the bit number in memory locations H and H from the bit number in memory locations H and H. The most significant eight bits of the two numbers are in memory locations H and H. Statement: Find the l's complement of the number stored at memory location H and store the complemented number at memory location H. Statement: Find the 2's complement of the number stored at memory location H and store the complemented number at memory location H.

Assume the least significant digit is stored at H. Statement:Read the program given below and state the contents of all registers after the execution of each instruction in sequence. Statement:Write a program to shift an eight bit data four bits right. Assume that data is in register C. Statement: Program to shift a bit data 1 bit left. Assume data is in the HL register pair. Statement: Write a set of instructions to alter the contents of flag register in Statement: Calculate the sum of series of numbers.

The length of the series is in memory location H and the series begins from memory location H. Consider the sum to be 8 bit number. So, ignore carries. Store the sum at memory location H.

Consider the sum to be 16 bit number. Store the sum at memory locations H and H. Statement: Multiply two 8-bit numbers stored in memory locations H and H by repetitive addition and store the result in memory locations H and H. Statement:Divide 16 bit number stored in memory locations H and H by the 8 bit number stored at memory location H. Store the quotient in memory locations H and H and remainder in memory locations H and H.

Statement:Find the number of negative elements most significant bit 1 in a block of data. The length of the block is in memory location H and the block itself begins in memory location H. Store the number of negative elements in memory location H. Statement:Find the largest number in a block of data. The length of the block is in memory location H and the block itself starts from memory location H. Store the maximum number in memory location H.

Assume that the numbers in the block are all 8 bit unsigned binary numbers. Statement:Write a program to count number of l's in the contents of D register and store the count in the B register. The certified experts and enthusiasts of microprocessor compile these reference books that the students can make use of for an enhanced preparation.

Here is a list of the best reference books for microprocessor, and the students can choose any of them to make their preparation the best one and have every knowledge about the topics:. Microprocessor and Microcontroller is a vast topic in which the microprocessor comes.

The syllabus of microprocessor contains many basic concepts, their definitions, examples, and other advanced topics and complex problems. Taking reference from the syllabus ensures that the students will follow the right track while preparing for the topics and start from the basic ones while moving towards the advanced ones. Microprocessor lecture notes free download material also contains the syllabus details of the topic, including the weightage of the topics and the related questions.

The sequence syllabus plays a vital role in the preparation as it helps the students to stay on track and avoid getting confused anytime. Furthermore, while following the right sequence for learning, the students will never go for the tougher topics first or the inter-related concepts in an inappropriate manner, and this will eventually ensure that they will understand everything well.

Additionally, learning according to the syllabus also helps the students in dividing the studies properly for every day, and thus get the proper preparation. While learning any topic, it is also essential to practice the important questions well and get a clear idea about the type of questions that might come in the exam, related to the particular topics. The important questions for microprocessor are mentioned below:.

Answer: microprocessor is an 8 bit one that is designed by Intel in It was generated using NMOS technology. The microprocessor is now used in many low-end as well as high-end electronic machines, including mobile phones, microwave oven, satellites, etc. Everything that this article includes is mentioned here: Introduction to Microprocessor Microprocessor Notes and Material Microprocessor Reference books Microprocessor Curriculum List of Microprocessor Important questions FAQs Introduction to Microprocessor Notes Eighty-eight-five microprocessor is an 8-bit microprocessor, designed in by Intel.

A program counters of 16 bits. On Terminal count, the output will go low for one clock period and becomes high again. This mode can be used for interrupt generation. MODE 5-Hardware Triggered Strobe: Counter starts counting after rising edge of trigger input and the output goes low for one clock period.

When the terminal count is reached, the counter is retrigerrable. On terminal count, the output will go low for one clock period and becomes high again.

A,CCH ;Clear display. FF repeated eight times. Clear C — register for Carry Get the data immediately. Get the data in A — reg. Get the value to be multiplied in B — reg. Multiply the two data The higher order of the result is in B — reg. The lower order of the result is in A — reg. Store the results. Get the value to be divided in B — reg. Divide the two data The quotient is in A — reg.

The remainder is in B — reg. The rotor motion occurs in a stepwise manner from one equilibrium position to next. The motor under our consideration uses 2 — phase scheme of operation. In this scheme, any two adjacent stator windings are energized. The switching condition for the above said scheme is shown in Table. Call the delay program Send the control word for motor rotation to the external device.

Pop up the values in stack and increment it. Decrement the count in R0. If zero go to next step else proceed to step 3. Perform steps 1 to 9 repeatedly. The digital data input and the corresponding output voltages are presented in the Table below. Errors if any will be displayed. In project window the status of all the registers will be displayed.

Click Go from Debug Menu. The results stored in registers will be displayed in Project window. Stop the Debug process before closing the application. Read number of bytes in the password 2.

Initialize the password 3. Blank the display 5. Read the key from user 6. Compare with the initialized password 7. Repeat the steps 6 and 7 to read next key 9. Vvs Kalyan Dec. Jessica Badolato Dec.
