Introduction

• We are living in the Embedded World. We are surrounded with many embedded products and our daily life largely depends on the proper functioning of these gadgets.
• Television, Radio, CD player of your living room, Washing Machine or Microwave Oven in the kitchen, Card readers, Access Controllers, Palm devices of our work space enable us to do many of our tasks very effectively.
• Apart from all these, many controllers embedded in the automobiles take care of many important operations.

What is this Embedded System?

• The computer you use to compose your mails, or create a document or analyze the database is known as the standard desktop computer. These desktop computers are manufactured to serve many purposes and applications. You need to install the relevant software to get the required processing facility.
• In contrast, embedded controllers carryout a specific work for which they are designed. Most of the time, engineers design these embedded controllers with a specific goal in mind. So these controllers cannot be used in any other place.
• Theoretically, an embedded controller is a combination of a piece of microprocessor based hardware and the suitable software to undertake a specific task.
• These days designers have many choices in microprocessors/microcontrollers. Especially, in 8 bit and 32 bit, the available variety really may overwhelm even an experienced designer. Selecting a right microprocessor may turn out as a most difficult first step and it is getting complicated as new devices continue to pop-up very often.
• In the 8 bit segment, the most popular and used architecture is Intel's 8051. Market acceptance of this particular family has driven many semiconductor manufacturers to develop something new based on this particular architecture. Even after 25 years of existence, semiconductor manufacturers still come out with some kind of device using this 8051 core.

RESUME WRITING TIPS FOR ENGINEERING STUDENTS APPEARING FOR CAMPUS PLACEMENT

Dear Students,

You are in the final year now and must be very excited about the campus placements. Final year students and fresh graduates often face the challenge of writing resumes that can effectively market them to recruiters. In such resume, one needs to shift the emphasis on academic achievements rather than professional achievements owing to the general lack of work experience.

Remember…..

• Even if you don’t have professional experience, your credentials are still worth noting down.

• You can use your resume to show employers the value you'll bring to their organization.

• The employer requires an account of skills that showcase one’s potential despite the lack of adequate work experience.

Follow the guideline given below while drafting Resume for campus placements:

• Resume should be well drafted in a short and concise format. An effective resume should constitute an education background and qualifications that are relevant to the job that is being sought. The language should be simple without use of unnecessary complex words.

• The resume should begin with your name and clear contact details.

• Use a summary of qualifications, rather than writing “objective” in the beginning. It's a great way to emphasize your academic record, skills in ways that will be meaningful to the employer. Highlight your academic record (if it is good), and your personality traits that best match with those required for the job.

• Do mention the important courses you took during engineering. Resume should reveal the skills you gained such as computer programming, technical writing, and project management skills.

• If you have earned any scholarships, awards then make note of them. Educational qualifications should be chronologically indicated along with the institutions that were attended.

• Include any internship or part-time jobs. Highlight any skills or achievements gained during that employment. Projects and extra curricular activities should be mentioned to show how the individual will contribute to the organization.

• Mention specific courses or training programs which you might have attended and which might give you a good edge over those who have only the required qualifications and work experience.

• Highlight the skills which you might have acquired through self learning. Be careful that you write only what you really know well. You can expect questions based on the skills you mentioned in the Resume.

• Don't be tempted to impress an employer by adding false details.

• Even though you are applying for your first job, follow a professional resume format, take time with your wording, and leave no spelling mistakes unattended!

• Overall be sure that you project a positive attitude and a willingness to jump and get things done.

VAN-NEUMANN ARCHITECTURE Vs HARVARD ARCHITECTURE

VAN-NEUMANN ARCHITECTURE	HARVARD ARCHITECTURE
Used in conventional processors found in PCs and Servers, and embedded systems with only control functions.	Used in DSPs and other processors found in latest embedded systems and Mobile communication systems, audio, speech, image processing systems
The data and program are stored in the same memory	The data and program memories are separate
The code is executed serially and takes more clock cycles	The code is executed in parallel
There is no exclusive Multiplier	It has MAC (Multiply Accumulate)
Absence of Barrel Shifter	Barrel Shifter help in shifting and rotating operations of the data
The programs can be optimized in lesser size	The program tend to grow big in size

Technical Writing for Engineering Students

MSBTE has included some excellent subjects like Development of Life Skills, Professional Practices etc  in the diploma curriculum that is implemented  in all the polytechnics in Maharashtra. These subjects, no doubt if implemented properly will benefit the engineering students immensely. 

Polytechnics under MSBTE are located in urban as well as rural places in  Maharashtra. MSBTE has given a lot of attention while designing syllabus so that the  balance can be maintained between rural Maharashtra and urban Maharashtra. I teach in one of the best Polytechnics in Mumbai .While conducting  practical sessions of subject " Professional Practices" I realize the need of emphasizing on developing Technical writing skills for the students. Preparing technical presentations, writing various technical reports such as design reports, progress reports, theses and dissertation are integral tasks in any Engineer's Life!  

These skills can also be developed by the students and taught by Lecturers while learning  core subjects but  most of the times these  things take back seat when it come to completing syllabus. We all are aware how a typical engineering student completes his "submission" at the last moment just before the deadline!  

My this post is to help students to learn  Technical writing. I will post links and articles here. I usually post  links under different post headings. For example "Tutorial Links", "Design Links" or post   related  to  links on mixed  topics  is labeled  as "Potpourri" .  But this time I thought of  writing  separate post  for links related to Technical writing because I don't want  to go this link unnoticed!  

Cheers!

Comparison between CAN and FIREWIRE

• The CAN bus offers a high-speed communication rate up to 1 M bits / sec, for up to 40 feet, thus facilitating real-time control. The original IEEE 1394 specifications allowed for speeds of 100, 200, and 400Mbps, IEEE 1394b provides speeds of 800, 1600, and 3200Mbps.

• CAN protocol can link up to 2032 devices (assuming one node with one identifier) on a single network. But accounting to the practical limitations of the hardware (transceivers), it may only link up to 110 nodes on a single network.FIREWIRE allows for the connection of up to 63 external devices.

  

• In CAN it is possible to add nodes to the bus without reprogramming the other nodes to recognize the addition or changing the existing hardware i.e. “Hot-plugging” is possible.FIREWIRE supports “Hot swapping” that is the ability to add and remove devices to a computer while the computer is running and have the operating system automatically recognize the change.

• CAN have gained widespread popularity for embedded control in the areas like industrial automation, automotives, mobile machines, medical, military and other harsh environment network applications.IEEE 1394 a very high-speed bus design that is ideal for high-bandwidth applications like multimedia..

Embedded SoftwareDevelopment Process

This article provides a generic description of the end-to-end process from C source file development to downloading machine code in the target processor. Details for a specific software suite coupled with a specific target controller may have slight differences.

As the system designer, you will write the C source files that implement the required control algorithm. The source files consist of C source code and also header files. Header files may include functions you have written, functions provided with your compiler, and also personality data for the specific processor you are using as the target system.

The C source files are compiled using a compiler for the specific target processor. The output from the compiler will be assembly code which is automatically routed to the assembler portion of the software development suite. The output from the assembler is object code which is linked with library files provided with the compiler.

The overall output will be machine code for download into the target processor. The software development suite may also provide some auxiliary files. These files provide information on memory usage and code placement within memory. These files are handy if system troubleshooting is required.

The machine code is downloaded into the target controller via a programming cable.
