Today's Personality

City Set in time

Defying the skyscrapers that have sprung up everywhere, there are still places in Hong Kong where you can enjoy its history 

Hong Kong has grown in leaps and bounds from the 1970s. In the process, many vintage and colonial-era buildings were razed to make way for glass skyscrapers. Still, if one cares to investigate, there are remnants of the past that still thrive.
Tai Kwun Centre for Heritage and Arts
In contrast to its original purpose, this police station and prison complex is today the Tai Kwun Centre for Heritage and Arts. A cultural hub, it also houses some of the city’s popular restaurants and bars. It has 16 heritage buildings and two new blocks that were built to host exhibitions and events. As I walk around the complex, I see a huge stage being set up. My guide, Fred Cheung, explains that one of the reasons Tai Kwun is popular is because it provides the much-needed public space that is scarce in the city.
The Central Magistracy and D Hall, is in the surviving wing of the prison. The authorities have tried to recreate what life in prison might have been like. The cells still have numbers over them and grated steel doors. The Prison Yard and the Parade Ground that were once seen as a symbol of oppression have now transformed into a performance space for theatre, music, dance and film.
Man Mo Temple
I am standing at the dimly-lit sanctum of the Man Mo Temple, enveloped in the aroma of incense and charmed by the red-and-gold ambience. Located at Hollywood Road, the temple is home to two deities, the god of literature (Man Tai) who holds a pen, and the god of war (Mo Tai) who wields a sword.
Dwarfed by surrounding skyscrapers, the approximately 170-year-old temple is a testament to Hong Kong’s cultural past and its people’s faith. The two deities at the temple were worshipped in imperial China by those either wishing to do well in the Civil Services exam or at martial arts. The temple still continues to draw students seeking blessings for better education and career prospects. The faithful write their wishes down on pieces of paper and offer them up along with a lamp at the altar. The architecture is extravagant with Chinese craftsmanship featuring ceramic figurines, intricate woodcarvings and murals.
Cheung Chau Island
I sail for an hour or so, away from the glassy façades of the city to the island of Cheung Chau, where ‘Hong Kongers go to breathe,’ I am informed. The bottle-green hills, the turquoise waters and buildings no taller than four storeys, make a refreshing change from the hectic metropolis.
Traditionally, the islanders practised fishing. However, in recent times, it has become a tourist attraction, not just for its natural beauty, but also for its sea food, cooked in traditional Cantonese style, and served in its many cafés.
The aroma of fish balls and steam buns is irresistible and I succumb to a spell of uncontrolled eating. My next destination is Cheung Po Tsai’s cave. Named after a notorious pirate of the 18th Century who ruled the South China Sea, the cave is all about narrow passages and steep treks. If you are claustrophobic, keep away and head to Pak Tai Temple instead.
Erected 200 years ago, the temple is dedicated to Pak Tai, the Taoist god of the sea. There is gold-plated woodcraft dating back to the Qing dynasty. If you crane your neck far enough, you will get an eyeful of the roof with its colourful ridges and ceramic figurines of dragons. It is also a good place to enjoy the silence, that is again a rare commodity back in Hong Kong.
Before leaving, I stroll on the sandy beaches of the island one last time, breathing in the quiet and then head to the ferry that bears me back to the hustle and roar of Hong Kong.


IIT-B researchers develop ‘Made in India’ microprocessor- AJIT has potential to reduce country’s dependence on imports

Engineers from the Indian Institute of Technology Bombay (IIT Bombay) have developed a microprocessor called AJIT, the first to be conceptualised, designed, developed and manufactured in India. The innovation, which has brought industry, academia and the government together, could reduce the country’s dependence on imports.
The project was funded by the Ministry of Electronics and Information Technology (MeitY) and IIT Bombay. Powai Labs, a Mumbai-based company, has invested in the venture, and will own, market and support the product.
Prof. Madhav Desai of the electrical engineering department and his team of nine researchers from IIT Bombay designed and developed the processor entirely at the institute. In a sense, the researchers have built the first proof of concept, Prof. Desai told The Hindu. “It is out of the laboratory, but not on the road yet. We are refining it. If successful, it will be mass produced.”
India’s electronics market is expected to reach $400 billion by 2020. Most of the electronic devices we use are imported; only a quarter of the devices are produced in the country.
An electronic equipment that is almost always imported is the microprocessor: the ‘brain’ of an electronic device. A microprocessor is an integrated circuit that contains a few million transistors (semiconductor-based electronic devices) fused on a semiconductor chip. It is just a few millimetres in dimension and is used in almost every electronic device, from the microwave and washing machine in homes to supercomputers of a space station. However, developing and manufacturing it is not easy; it is expensive, risky, and needs skill. Hence, only a handful of companies across the world have been able to manufacture and sell microprocessors.
If a microprocessor is home-grown, manufacturers of electronics devices could benefit from the ready availability and competitive price of an Indian device with an added advantage of having the design and support team nearby. “Geographical proximity could easily make it possible to get something done in say two weeks, instead of three months required otherwise,” Prof. Desai said.
Prof. Desai and his team developed a tool set called AHIR-V2, which can convert an algorithm to hardware to design the microprocessor circuit. AJIT (named after Prof. Desai’s friend and mentor who died in an accident a few years ago), is a medium-sized processor. It can be used inside a set top box, as a control panel for automation systems, in a traffic light controller or even robotic systems. What’s more, the researchers expect AJIT to cost as little as 100 when it is produced en masse.
Prof. Desai said he saw the microprocessor in use in embedded systems. “It’s not for mobile phones yet but not for trivial uses like washing machines either. We can do serious things with it, like use it in WiFi routers, secure power metres or even electronic voting machines.”
In the first stage, AJIT has been manufactured in the government-owned Semiconductor Laboratory, Chandigarh. It has a technology that offers the smallest building block of the size 180 nanometres (nm). The researchers plan to commercially manufacture the processor using more advanced techniques that provide the smallest building block of size 65 nm or 45 nm, which is state of the art. “Fabricating this using 180 nm technology is the first step. Although this may not be state-of-the-art technology, it is enough for most of the targeted applications. Using advanced technology for large manufacturing quantities — tens of lakhs — would bring the cost per piece down,” Prof. Desai said.The researchers have made the software tools associated with AJIT freely available. The processor is also available as a ‘softcore’, where vendors can buy a licence to use the design of the microprocessor and fabricate it to use it in their system. The researchers also offer to customise the processor for specific applications, and plan to introduce AJIT to academia. “A well-designed single-board computer system could be made available at a low cost for students and other enthusiasts to experiment with,” he said.
Building the indigenous microprocessor came with its set of challenges. Prof. Desai had only a small group graduate students who worked on a shoestring budget.
When the team started work in 2015, they were clear it would be a five-year effort. “The first year was about getting the first implementation, and building a prototype. And then validate the prototype and get it manufactured.”
There are tougher challenges ahead. “We need to get more people to use AJIT. If the business community would own this processor, build systems around it so that users, as well as supporters, see value in this and can make money from the effort, then this effort can remain sustainable,” Prof. Desai said.
Verification of the system, he said, was very complex. “It takes effort and ingenuity. It is up to us as a research and development organisation to take it to its proper culmination,” Prof. Desai said.
MeitY has extended its funding to enhance the processor and deploy it in government-initiated projects. SAMEER (Society for Applied Microwave Electronics Engineering & Research), an independent laboratory under MeitY, is planning to use AJIT in the receivers being developed for NAVIC or IRNNS (The Indian Regional Navigation Satellite System), an indigenous navigation system for the Indian subcontinent.
