Megachips, now that they have SITIme will put that bit together with the other ones they have for an IoT SoC.

So what do they have anyway?

but before scanning this one.

Nice QUIK,  when those new job are filled another 20 yrs of experience will have been added,  a lot to do, and I look forward to reading of the end results of these efforts in '15.  Well over 100 man yrs of experience added this past 12 months.  As an investor in their business the best thing for me to gain insight not discussed is in those numerous listings of the past 12 months.


Notice of Development of Sensor Hub LSI “frizz”
MegaChips Corporation (“the Company”) announces that it has developed the Sensor Hub LSI “frizz”
(Model No.: MA60000). The Company is scheduled to begin delivering samples at the end of October 2014
and shipping commercial products in January 2015. The FY2015 sales target for the product is 10 million
units. The details of the product are outlined below.
Currently, smartphones and wearable devices (activity meters, smart watches, etc.) are equipped with
multiple sensors including acceleration sensors, gyro sensors, and terrestrial magnetism sensors. These
sensors have led to new utilizations, including recognition of the human movement or the state of a device,
either to control the device or to record the human activity. When the main processor processes these data
from the sensors, the power consumption of the device increases significantly. To solve this problem, an
LSI called the Sensor Hub has been developed. The Sensor Hub is located between the main processor and
the sensor. While the main processor is not working, the Sensor Hub with its “Always on” function
constantly receives signals from the sensor and buffer them. The newly developed “frizz” is not just a hub
for the buffer, but a next-generation Sensor Hub LSI with DSP that performs advanced arithmetic
processing with low power consumption.
For smartphones, which continue to advance rapidly, battery life is a key issue. In addition, in the evolution
of smartphones, functions that are expected to spread rapidly include “status detection”, to detect the status
of holding a data terminal, “behavior recognition”, to detect behaviors such as walking and taking the train,
and “Pedestrian Dead-Reckoning (PDR)”, to realize a navigation system in locations where GPS radio
waves cannot be received. To achieve these functions, a high-performance Sensor Hub LSI with low power
consumption is essential. In order to meet this demand, the “frizz” is equipped with an exclusively designed
DSP for data processing with low power consumption. For example, the DSP processes heavy operations
including the orientation estimation used in PDR with a parallelized arithmetic processing circuit. As a
result, low clock operation with ultra-low power consumption becomes possible.
To prepare for the upcoming aging society, the area of wearable devices that use a variety of sensors for
healthcare and monitoring of the elderly and children is where strong growth is expected in the future. In
this area, the “frizz,” taking advantage of the Sensor Hub LSI based on DSP, responds to not only motion
sensors for acceleration and gyro, but a biosensor for which complex processing is required, including
pulse detection. In addition, the Company is advancing the creation of a library of software for processing
and operating all sorts of sensors to contribute to the rapid launch of its customers’ products. MegaChips Corporation 2/2
For the software development environment, an Eclipse-based Integrated Development Environment (IDE)
has been prepared and developers can create software using “C/C++,” which is what they are accustomed
to using. In addition, as an evaluation kit, the Company has prepared an evaluation board with ten sensors
including acceleration, gyro, terrestrial magnetism, and atmospheric pressure to allow the evaluation of
the software developed.
Upon the release of the “frizz,” Kenji Nakamura (Officer and Deputy General Manager, Division No.2,
AS Business Headquarters, which is responsible for the ASSP product business) makes the following
comments: “Our ‘frizz’ is a high-performance Sensor Hub LSI with ultra-low power consumption that will
significantly change the world of smartphones and wearable devices. We are proud that we are able to
provide products that make your lives safe, secure, and comfortable, including a navigation system for
underground malls and buildings and a remote monitoring system for children and the elderly.”

Like audience who bought the IP algo house SPI, they are also DSP based...won't match the approach that QUIK has taken as far low power.........but notice that bits and pieces are not sticking around very long, they are gone a lot of the time.
