In embedded systems, modeling the performance of off-the-shelf processors is very important to
enable the designer to estimate the capability of each candidate processor against the target
application. Considering the large number of available embedded processors, the need has increased
for building an infrastructure by which it is possible to estimate the performance of a given
application on a certain processor with a minimum of time and resources. This paper presents
the use a Xilinx MicroBlaze softcore processor as a reference model augmented by FPGA-based
profiling mechanism to extract the functional statistics that characterize the target application.
Linear regression analysis is implemented for mapping the application functional behavior on the
reference model (MicroBlaze) to the performance of the candidate processors.
From our perspective [this situation] gives us more breathing room to be clever about
design. Most people run to the current process node as fast as they can. That's going to
change. Instead of running to the next node, you will come up with new architectures and
circuit designs, and that will create more opportunities on the design side, bringing more
value to a company like Broadcom.
Qualcomm vs. Broadcom: Race on China’s BeiDou Nav System
China’s BeiDou satellite navigation system has become the biggest bone of contention in the
Qualcomm vs. Broadcom competition to deliver more accurate positioning information to mobile devices.
Qualcomm announced late last month its support for the BeiDou constellation within Qualcomm IZat
location solutions. The San Diego-based company revealed its collaboration with Samsung to launch
the first wave of BeiDou-enhanced consumer smartphones.
As many as 11.5 million small-cell base stations could be deployed by 2018, up from just
168,000 today, according to a status report from the Small Cell Forum. The trade group gave
the update and released guidelines on using the systems in businesses as part of a regular meeting in Dallas today.
Small-cell base stations are seen as an inexpensive way to add capacity quickly to cellular
networks swamped with mobile data from the rise of smartphones and tablets.
Which is More Important -- Technology or Marketing?
Some people argue that the key for start-up is marketing, aka, searching for product-market
fit, while other people argue the key is really making good product. All you need to do is make a great product.
This reminds me of a joke about the military. When the general asks a solider what is important
in army, the solider doesn't say combat training or better weapon, but he said "women". Why?
Because there is no women in the army. The moral of this story is people tend to think what they
don't have is important.
MIPI, which stands for Mobile Industry Processor Interface, was originally conceived as a
low-power interface intended to interconnect functional units (e.g., camera sensors and displays) within handsets.
This has led to an interesting dilemma. Since MIPI as an interface was never intended to
serve non-mobile applications, interfacing to FPGAs was never made a priority. This makes
perfect sense, since the majority of FPGAs are not well-suited for use in high-volume mobile
devices. On the other hand, FPGAs are quite common in medical, industrial, and automotive applications.
The end result is that the lure of using low-cost MIPI-enabled devices and the need to connect them to
FPGAs has forced designers to look for bridging solutions.
