Using CNNs To Speed Up Systems
By Ann Mutschler - 10 Aug, 2017 - Comments: 0

Convolutional neural networks (CNNs) are becoming one of the key differentiators in system performance, reversing a decades-old trend that equated speed with processor clock frequencies, the number of transistors, and the instruction set architecture. Even with today's smartphones and PCs, it's difficult for users to differentiate between processors with 6, 8 or 16 cores. But as the amount o... » read more

CCIX Enables Machine Learning
By Brian Bailey - 31 Jul, 2017 - Comments: 5

It takes a lot of technology to enable something like machine learning, and not all of it is as glamorous as neural network architectures and algorithms. Several levels below that is the actual hardware on which these run, and that brings us into the even less sexy world of interfaces. One such interface, the Cache Coherent Interconnect for Accelerators (CCIX), pronounced C6, aims to make th... » read more

Hardware/Software Tipping Point
By Brian Bailey - 08 Jun, 2017 - Comments: 0

It doesn't matter if you believe [getkc id="74" comment="Moore's Law"] has ended or is just slowing down. It is becoming very clear that design in the future will be significant different than it is today. Moore's law allowed the semiconductor industry to reuse design blocks from previous designs, and these were helped along by a new technology node—even if it was a sub-optimal solution. I... » read more

Supporting CPUs Plus FPGAs (Part 3)
By Brian Bailey - 19 Apr, 2017 - Comments: 0

While it has been possible to pair a CPU and FPGA for quite some time, two things have changed recently. First, the industry has reduced the latency of the connection between them and second, we now appear to have the killer app for this combination. Semiconductor Engineering sat down to discuss these changes and the state of the tool chain to support this combination, with Kent Orthner, system... » read more

Rethinking Computing For The AI Age
By Govind Wathan - 13 Apr, 2017 - Comments: 0

Cisco estimates that global cloud IP traffic will nearly quadruple in the next five years. Information consumption is exploding with artificial intelligence (AI) embedded into all devices and experiences surrounding us. However, we do not want that to come at a cost of our security and privacy. Talk about pressure. On you. Today, much of computing is done in the cloud for things that you are... » read more

Embedded FPGAs Come Of Age
By Ann Mutschler - 27 Feb, 2017 - Comments: 0

FPGAs increasingly are being viewed as a critical component in heterogeneous designs, ratcheting up their stature and the amount of attention being given to programmable devices. Once relegated to test chips that ultimately would be replaced by lower-power and higher-performance ASICs if volumes were sufficient, FPGAs have come a long way. Over the last 20 years programmable devices have mov... » read more

Tuning Heterogeneous SoCs
By Brian Bailey - 08 Dec, 2016 - Comments: 0

It's one thing to pack multiple processor cores into a design, but it is much more difficult to ensure the hardware matches the software's requirements, or that the software optimally uses the hardware. Both the hardware and software teams are now facing these issues, and there are few tools to help them fully understand the problems or to provide solutions. Design teams continue to add more... » read more

System Performance Analysis At ARM
By Arm - 07 Dec, 2016 - Comments: 0

Performance analysis is a vital task in modern SoC design. An under-designed SoC may run too slowly to keep up with the demands of the system. An over-designed SoC will consume too much power and require more expensive IP blocks. At ARM we want to help our partners build SoCs that deliver the best performance within their power and area budgets. The simple truth is that this is more difficul... » read more

Teaching Computers To See
By Ann Mutschler - 16 Nov, 2016 - Comments: 0

Vision processing is emerging as a foundation technology for a number of high-growth applications, spurring a wave of intensive research to reduce power, improve performance, and push embedded vision into the mainstream to leverage economies of scale. What began as a relatively modest development effort has turned into an all-out race for a piece of this market, and for good reason. Mark... » read more

Heterogeneous System Challenges Grow
By Ann Mutschler - 03 Oct, 2016 - Comments: 0

As more types of processors are added into SoCs—CPUs, GPUs, DSPs and accelerators, each running a different OS—there is a growing challenge to make sure these compute elements interact properly with their neighbors. Adding to the problem is this mix of processors and accelerators varies widely between different markets and applications. In mobile there are CPUs, GPUs, video and crypto pr... » read more
