Looks like IOT era started - Chip companies catching up

Broadcom and Qualcomm chipmaking companies has been on a shopping spree....

Broadcom aquired Brocade, specialises in data storage and networking, while Broadcom provides connectivity components, like Wi-Fi chips, to companies like Apple, HTC and LG. The move comes at a time where data centres are increasingly important, thanks to the advent of the Internet of Things (IoT) as IoT technology is responsible for connecting regular old objects, like lights, fridges and dishwashers, to the internet. As more appliances become smart, and autonomous cars drive in our near future, greater data storage is needed.

On the other hand Qualcomm aquired NXP Semiconductor for expertise in security, identity and automotive processor components, to complement its mobile, IoT and wireless radio business. It’s a smart move by Qualcomm to help it continue to be a key player in the chip industry, as connected vehicles with increasing amounts of on-board tech, and digital security in general, become areas where more attention and investment is focused.

Broadcom buys Brocade for data centre cloud

The chip industry has been undergoing rapid consolidation as companies try to capture market share, much of it related to connected devices and cars, and Avago/Broadcom has been one of the sector's most prolific acquirers.

The deal, the latest in a consolidating chip sector, will allow Broadcom to corner a larger share of the data center products market by using Brocade's fiber channel switches that speed up data transfer between servers and storage devices.

Singapore-based Broadcom, formerly Avago Technologies, is known for its connectivity chips used in products ranging from mobiles to servers, while California-based Brocade makes networking switches, software and storage products.

The market for IT infrastructure products is expected to expand rapidly. Total spending on cloud infrastructure, including server, storage and ethernet switches, will increase by 15.5 percent to $37.1 billion in 2016, according to research firm IDC.

Broadcom said it planned to sell Brocade's networking business, which makes controllers and access points that help businesses offer high-speed internet to their customers, to avoid competing with its top customers such as Cisco, Hewlett Packard Enterprise and Intel Corp.

Since taking over the top job at Avago a decade ago, Chief Executive Hock Tan has turned around a small chipmaker into a giant with a market capitalization of $67 billion.

As the chip industry has been undergoing rapid consolidation, the biggest chip deal ever, smartphone chipmaker Qualcomm Inc agreed last week to buy NXP Semiconductors NV for about $38 billion, making it the leading supplier to the fast-growing automotive chips market.

Looking for MS in USA, GRE , TOFEL & US VISA Be Careful ! Learn to write computer programs

Nearly 25 of the 60 students in the program must leave. It is because they were unable to write computer programs, a necessary part of the curriculum and a skill that United States schools teach to undergraduates. So students be careful it will be applied to other universities in US as well in the near future.
Learn C skills, write programs and get programming skills required for US universities.

Embedded System Concepts

1. What is an Embedded System? Give some examples of
embedded system in daily life.

Ans. Embedded System is a system which hides a small computation unit inside. This computer is not general purpose computer like our Desktop PC but a small micro controller or microprocessor. Embedded System is designed to perform specific tasks. Best example of an Embedded System is our mobile phone which includes a processing unit or no. of processing units along with peripherals like keypad/touchpad, touch screen, LCD, Communication modules etc.
There are other examples like Electronic System in washing machine, ATM machine, front panel of Microwave oven, printers, TV, set top boxes, Remote control, Dashboard of a 4-wheeler and many more. If you observe carefully we are surrounded by a no. of embedded system and use them very frequently in our day to day life.

2. What are basic features of an Embedded System?
Ans. A good embedded system must possess following features…
• Microcontroller based
• Software driven
• Reliable
• Real time control system
• Autonomous and human interactive
• Operating on diverse physical variables
• Operating in diverse environments

3. What are various categories of an Embedded System based on complexity?
Ans. Embedded Systems can be broadly classified in three categories…
a. Small Scale – 8/16 bit CPU, little hardware, less software
complexity, no RTOS, battery operated.
b. Medium scale – 16/32 bit uC or DSPs, Complex hardware and
software design, RTOS source code engg tool, IDE.
c. Sophisticated – Configurable processors, Cutting edge applications, highly complex hardware and software design.

4. Why PC can’t be treated as an Embedded System?
Ans. Of course PC is also embedded with a processing unit but still it can not be called as an Embedded System. The reason is very clear that PC is not supposed to do a specific task. For a bank employee PC is accounting add for his work while for an engineer it is designs add. For a doctor PC helps to analyze patient reports and for children it’s more like video game or a communication system to stay connected with their friends through social networking websites. Hence PC has different applications for different people; hence it cannot be treated as an
embedded system.

5. What is difference between a PC based System and an Embedded System?
Ans. A PC based system is bulky hence difficult to be deployed specially in remote areas. For example if one wants a data logger system to monitor all the processes and events in an aircraft or on a hilly area, PC is never a suitable option. In this case an Embedded System can do the job well consuming very small space. Also PC based system are not so cost efficient and as reliable as embedded systems.

6. Ok if embedded systems are so important and popular than why PCs still exist, why can’t we use embedded systems instead of PCs?
Ans. Well PC works with operating systems and they support comprehensive cross compilers for generating executable files for embedded systems. Hence we can never ignore the importance of PCs.

7. What are the main components of an Embedded System?
