If there are 8 opcodes and 10 registers, a. What is the minimum number of bits required to represent the OPCODE? b. What is the

Nimfa-mama [501]

Answer:

For 32 bits Instruction Format:

OPCODE DR SR1 SR2 Unused bits

a) Minimum number of bits required to represent the OPCODE = 3 bits

There are 8 opcodes. Patterns required for these opcodes must be unique. For this purpose, take log base 2 of 8 and then ceil the result.

Ceil (log2 (8)) = 3

b) Minimum number of bits For Destination Register(DR) = 4 bits

There are 10 registers. For unique register values take log base 2 of 10 and then ceil the value. 4 bits are required for each register. Hence, DR, SR1 and SR2 all require 12 bits in all.

Ceil (log2 (10)) = 4

c) Maximum number of UNUSED bits in Instruction encoding = 17 bits

Total number of bits used = bits used for registers + bits used for OPCODE

= 12 + 3 = 15

Total number of bits for instruction format = 32

Maximum No. of Unused bits = 32 – 15 = 17 bits

OPCODE DR SR1 SR2 Unused bits

3 bits 4 bits 4 bits 4 bits 17 bits

Create a java class for Bank Accounts with these public String attributes: ownerName, acctNbr and these private double attribute

Readme [11.4K]

Answer:

public class BankAccounts

{

public String ownerName;

public String acctNbr;

private double debits;

private double credits;

public BankAccounts(String ownerNm, String acNum)

{

debits = 0;

credits = 0;

ownerName = ownerNm;

acctNbr = acNum;

}

public void addDebit(double debitAmt)

{

if(credits > (debits + debitAmt))

debits = debits + debitAmt;

else

System.out.println("Insufficient balance");

}

public void addCredit(double creditAmt)

{

credits = credits + creditAmt;

}

public double getBalance()

{

double balance = 0;

if((credits - debits) > 0) // return the value if there is actually some balance left.

balance = credits - debits;

return balance; //returns 0 if credits are lesser or equal to debits

}

Explanation:

Here class name is BankAccounts which can be used to create a new bank account whenever any user wants to open a bank account. This class will help to track any new account opening, debits and credits operations carried out on that account.

We have a constructor here, which accepts 2 arguments i.e. Bank account Owner Name and Account Number. The constructor also sets the values of debits and credits as 0.

The methods addDebit(), addCredit() and getBalance() help to perform Debit and Credit operations on the account.

NOTE: The method getBalance() returns a positive value only when credits are greater than debits.

The method addDebits() can add debits only as the condition that the credits are greater than the resultant debits.

The code for class BankAccounts is hereby attached.

Why is my computer fans making weird noises?

sattari [20]

Answer:

The biggest culprit for excess noise in computers Computer internal devices all generate "heat." Most computers manufacturer add temperature controller fans on important internal devise or locations. These will spin faster when "hot" temperatures are detected. With the fans, there are usually "ventilation holes" needed to push this hot "air" out. Unfortunately, these holes let in dust and "other debris' into the fans, thus making them "spin" harder and faster. This is normal. You might want to take your computer to your school's office and ask them about your. computer. I think I have a solution below but I am not sure it will work.

Check to make sure that your computer is set to use all of your speakers. Navigate to the Control Panel, and double-click Sounds And Audio Devices. If you change this setting, click Apply, OK, and then OK again to exit the Sounds And Audio Devices Properties dialog box.

Hope this answer helped you have a good day. :)
