ECET 330 DeVry Complete Week Discussions Package

ECET 330 DeVry Week 1 Discussion 1

Microprocessor and Microcontroller Difference (graded)

Discuss the differences between microcontrollers and microprocessors. Discuss the applications of a microprocessor or microcontroller for different industries

ECET 330 DeVry Week 1 Discussion 2

Memory Map and Different Types of Memory (graded)

What does the memory model of a microcontroller show? Discuss the reasons for different types of memory such as RAM, EEPROM, and FLASH used in HCS12.

 

ECET 330 DeVry Week 2 Discussion

Different Types of HCS12-Addressing Modes (graded)

Addressing modes are different ways that an operand can be accessed. Discuss different types of addressing modes of HCS12. What is a relative addressing mode? What is the difference between a direct and an extended addressing mode? Discuss how Registers X and Y are used in index addressing mode.

 

ECET 330 DeVry Week 3 Discussion 1

Stack and Subroutines (graded)

Discuss the role of stack in subroutine calls. What are different techniques of passing values to a subroutine? This section lists options that can be used to view responses.

 

ECET 330 DeVry Week 3 Discussion 2

Relative Addressing Mode (graded)

Discuss relative addressing mode. Which instructions use this addressing mode? What is the difference between a short branch and a long branch?

 

ECET 330 DeVry Week 4 Discussion 1

I/O Ports of MC9S12G128 (graded)

Some ports of the MC9S12G128 microcontroller have other functions besides being a general purpose I/O. Discuss the functions of each port of this microcontroller.

 

ECET 330 DeVry Week 4 Discussion 2

Masking Techniques and Bit Addressability (graded)

Sometimes, we want to monitor only a few bits of an input port. Also, sometimes we want to send an output to only one bit of a port. Discuss some of the ways that we can achieve these objectives.

 

ECET 330 DeVry Week 5 Discussion 1

Negative Number Representations (graded)

HCS12 uses 2’s complement representation for negative numbers. Discuss other techniques used for representing negative numbers inside CPUs. Talk about the advantage of 2’s complement over the other representations. Show some examples of how numbers are represented using each technique.

 

ECET 330 DeVry Week 5 Discussion 2

Instructions Used for Signed and Unsigned Numbers (graded)

This week, we are talking about different instructions for signed and unsigned numbers. Discuss the carry, overflow, and N flag. How does CPU know if you are using a number as a signed number or as an unsigned number? Discuss the different instructions used for signed or unsigned numbers. For example, what is the difference between signed multiplication and unsigned multiplication? What is the difference between shifting a signed number and shifting an unsigned number

ECET 330 DeVry Week 7 Discussion 1

Bus Contention (graded)

In your own words, describe bus contention and how to avoid this problem. What techniques are used in modern computer systems to avoid bus contention?

 

ECET 330 DeVry Week 7 Discussion 2

Fan-Out and Reduced-Drive Registers (graded)

Discuss HCS12 port fan-out and reduced-drive registers. Discuss the role of the chip 74LS244 for driving multiple inputs. This section lists options that can be used to view responses
