Adapt Or Perish: A Unified Theory Of Coherency


Evolution is a natural process and more importantly a relatively slow process that has eventually got us here, capable of perceiving, analyzing, and handling complex tasks. As our environment, society, and surroundings became more complex we learned how to adapt at a brisk and instantaneous manner, in this melting pot of a heterogeneous world. The evidence can be seen in all ages, from the poli... » read more

Why Is Semiconductor Schedule Predictability Boring?


Why is it not sexy to talk about the manageability of system-on-chip (SoC) projects? As an IP vendor, we are constantly bombarded with questions about how our technology can enhance performance, reduce latency, and lower power consumption. At the same time, reducing cost and time to market for the SoC design conflict with these requirements, even though they rank right up there among the top en... » read more

Exploring System Architectures For Data-Intensive Applications


The exponential growth of digital data is being driven by a number of factors, including the burgeoning Internet of Things (IoT) and an increased reliance on complex analytics extracted from extremely large data sets. Perhaps not surprisingly, IDC analysts see digital data doubling roughly every two years. This dramatic growth continues to challenge, and in some cases, even outpace industry cap... » read more

Which Memory Type Should You Use?


I continue to get besieged by statements in which memory “latency” and “bandwidth” get misused. As I mentioned in my last blog, latency is defined as how long the CPU needs to wait before the first data is available, while bandwidth is how fast additional data can be “streamed” after the first data point has arrived. Bandwidth becomes a bigger factor in performance when data is stor... » read more

Inside The 5G Smartphone


Amid a slowdown in the cell phone business, the market is heating up for perhaps the next big thing in wireless—5th generation mobile networks or 5G. In fact, major carriers, chipmakers and telecom equipment vendors are all rushing to get a piece of the action in 5G, which is the follow-on to the current wireless standard known as 4G or long-term evolution (LTE). Intel, Samsung and Qualcom... » read more

The Memory And Storage Hierarchy


The memory and storage hierarchy is a useful way of thinking about computer systems, and the dizzying array of memory options available to the system designer. Many different parameters characterize the memory solution. Among them are latency (how long the CPU needs to wait before the first data is available) and bandwidth (how fast additional data can be “streamed” after the first data poi... » read more

Optimizing Analog For Power At Advanced Nodes


As any engineering manager will tell you, analog and digital engineers seem like they could be from different planets. While this has changed somewhat over time, [getkc id="52" comment="analog"] is still something of a mystery to many in [getkc id="81" kc_name="SoC"] design teams. Throw power management into the mix and things really get interesting. Improvements in analog/mixed-signal tools... » read more

Memory Architectures Undergo Changes


By Ed Sperling Memory architectures are taking some new twists. Fueled by multi-core and multiple processors, as well as some speed bumps using existing technology, SoC makers are beginning to rethink how to architect, model and assemble memory to improve speed, lower power and reduce cost. What’s unusual about all of this is that it doesn’t rely on new technology, although there certai... » read more

Experts At The Table: Latency


By Ed Sperling Low-Power/High-Performance engineering sat down to discuss latency with Chris Rowen, CTO at Tensilica; Andrew Caples, senior product manager for Nucleus in Mentor Graphics’ Embedded Software Division; Drew Wingard, CTO at Sonics; Larry Hudepohl, vice president of hardware engineering at MIPS; and Barry Pangrle, senior power methodology engineer at Nvidia.
