Windows CE to stay here ? A ‘Real-time’ analysis.

Windows CE to stay here ? A ‘Real-time’ analysis.

After the advent of windows on ARM/Windows Phone 8, there is always a concern among the windows CE community on the future of Windows CE. When compared to windows on ARM/windows phone 8 there are many reasons to believe that windows CE is here to stay, in this blog I compare one of the interrupt handling features – priority inheritance mechanism, of Windows CE that determines its real-time capability. How predictable and reliable a system is, on reacting to an interrupt, defines its real-time effectiveness. When a common resource is shared among 3 tasks using Mutex there is a possibility of a situation where the high priority task had to wait for the lower priority task to release the shared resource. In this case the high priority  task remains blocked, causing a priority inversion situation where high priority task is indirectly pre-empted by a low priority task, effectively “inverting” the relative priorities of the two tasks, meaning the high-priority task has to wait for the completion of the lower...

Rich Communication Services

Rich Communication Services

Today in this digital world, almost everyone wants to be connected from anywhere and anytime. This is leading to high data usage day-by-day. People are looking for unified communication services beyond voice and SMS/MMS. Over-The-Top players like Skype, Whatsapp have maximized their business by provided IP based chat and call services. Even though the market needs are addressed by the OTT players, OTT couldn’t guarantee QoS, security and interoperability. On the other hand operators started losing revenue to OTT players. For example, an OTT provider named KakaoTalk has been extremely successful with its messaging services, supporting 37 million users in Korea and 46 million globally. Therefore, Korean service providers are “experiencing difficulties, including decreased SMS revenues and increased network investment cost to accommodate surging traffic,” per South Korean service provider. This has led to the “Service Provider vs OTT wars”. To handle these conflicts of interest, GSMA including Operators, OEMs and ISV formed a body to govern specifications to provide Rich Communication Services (RCS). RCS is a multimedia communication...

Next Phase of Mobile Computing – Making everything Smart

Next Phase of Mobile Computing – Making everything Smart

Do you think your smartphone is a ‘smart’ one? Yet not. The technology that powers the device is yet to catch up well everywhere and the world around us to transform radically. The first phase of mobile computing was all about turning our cellphones into powerful pocket PC’s. This posed unique challenges because of the size and data connectivity. Over the last decade, cellphone witnessed convergence of technologies with significant proliferation of data and voice. Once the size seemed to be squeezing and then started to become bulky with large screen displays. Within this process tablets were born. Multiple segments of devices were created. The local connectivity technologies converged, and coherently evolved to become robust. The cellular technologies bettered by specifications and eventually on the data rates. The semiconductor industry had undergone convergence & consolidation to produce stable, integrated, powerful, fast and efficient hardware platforms. The web services to connect to the internet were redefined and internet on the device became more prevalent with quick access to any data....
