Design Complexity In The Golden Age Of Semiconductors
By Frank Schirrmeister - 24 Aug, 2023 - Comments: 0

While writing last month's blog that used some of the trend charts we have seen, I noticed that a lot of the data ends in 2020 or earlier, but I was too close to the deadline to sit down and make orderly updates to some of the charts. Working day-to-day in the area of SoC integration and networks-on-chips (NoCs), the classic chart based on Karl Rupp's now 50 years of processor data that overlay... » read more

What Does 2023 Have In Store For Chip Design?
By Brian Bailey - 26 Jan, 2023 - Comments: 0

Predictions seem to be easier to make during times of stability, but they are no more correct than at any other period. During more turbulent times, fewer people are courageous enough to allow their opinions to be heard. And yet it is often those views that are more well thought through, and even if they turn out not to be true, they often contain some very enlightening ideas. 2022 saw some ... » read more

Is UCIe Really Universal?
By Brian Bailey - 22 Nov, 2022 - Comments: 3

Chiplets are rapidly becoming the means to overcome the slowing of Moore's Law, but whether one interface is capable of joining them all together isn't clear yet. The Universal Chiplet Interconnect Express (UCIe) believes it will work, but some in the industry remain unconvinced. At least part of the problem is that interconnect standards are never truly finished. Even today, the protocols tha... » read more

High-Level Synthesis For RISC-V
By Brian Bailey - 28 Oct, 2021 - Comments: 2

High-quality RISC-V implementations are becoming more numerous, but it is the extensibility of the architecture that is driving a lot of design activity. The challenge is designing and implementing custom processors without having to re-implement them every time at the register transfer level (RTL). There are two types of high-level synthesis (HLS) that need to be considered. The first is ge... » read more

Vtech: Bus Performance, FPGA Debug
By Brian Bailey - 15 Jul, 2020 - Comments: 0

It has been a long time since I was able to talk about a new verification company, but today I can introduce you to Verification Technology, or Vtech for short. If you do a search for them, you will probably find a company that sells baby monitors and kids toys. This is not that company. So, let's make sure you have the right web address to start with https://vtech-usa.com/ or https://vtech-inc... » read more

Mixing Interface Protocols
By Ann Mutschler - 21 Dec, 2017 - Comments: 0

Continuous and pervasive connectivity requires devices to support multiple interface protocols, but that is creating problems at multiple levels because each protocol is based on a different set of assumptions. This is becoming significantly harder as systems become more heterogeneous and as more functions are crammed into those devices. There are more protocols that need to be supported to ... » read more

Supporting CPUs Plus FPGAs
By Brian Bailey - 11 Apr, 2017 - Comments: 5

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

Correlating Software Execution With Switching Activity To Save Power In SoC Designs
By Russell Klein - 09 Mar, 2017 - Comments: 0

There is probably no more pointless waste of energy than lighting and heating a room that is empty. The obvious optimization: notice that no one is there and turn off the lights. It works the same on an SoC or embedded system. To save energy, system developers are adding the ability turn off the parts of the system that are not being used. Big energy savings but with no compromise to functional... » read more

An Easier Path To Faster C With FPGAs
By Zibi Zalewski - 22 Nov, 2016 - Comments: 0

For most scientists, what is inside a high-performance computing platform is a mystery. All they usually want to know is that a platform will run an advanced algorithm thrown at it. What happens when a subject matter expert creates a powerful model for an algorithm that in turn automatically generates C code that runs too slowly? FPGA experts have created an answer. More and more, the genera... » read more

Introduction To AXI Protocol
By Aldec - 29 Sep, 2016 - Comments: 0

By Brandon Wade When part of a team, your group can become more capable than a single individual, but only if your team can work together and communicate effectively. Having members of a group talk over each other leads to nothing but a cacophony, and nothing gets done. For this reason protocols need to be established, such as letting others speak without interruption, or facing those you ar... » read more
