A New Standard for FPGA Peripherals

FPGA boards are quite possibly the most versatile and useful tools in our engineering hardware toolboxes. A competent hardware engineer can grab an FPGA board and pretty quickly solve a wide variety of problems and challenges. Need to accelerate an algorithm in hardware? Want to process data coming in from high-speed peripherals? Have some interconnect, buffering, sensor fusion, or other challenging interface problem? An FPGA board … Read More → "A New Standard for FPGA Peripherals"

SiFive Aims to Change the World

“Call me Ishmael.” – Herman Melville, “Moby Dick”

Call me a skeptic.

There are lots of microprocessor architectures in the world. Maybe too many. There are even plenty of free and open-source processor options. Processors are like opinions: everybody has one. So why is RISC-V any different? What makes anyone think that RISC-V … Read More → "SiFive Aims to Change the World"

Plumbing for High Performance Computing

In this week’s episode of Fish Fry, data center technology rules the roost. We can toil away at the world’s greatest IoT design, embedded computer, or specialized IC – but it’s the diligence of datacenter technology that holds the key to the success of our electronic design community. In this week’s Fish Fry, we take a closer look at two different aspects of data … Read More → "Plumbing for High Performance Computing"

System Delta Sigma Delta

System Design is inherently a task of integration. The job of the system engineer is to gather and integrate a collection of components which, taken together, will solve some problem, while meeting a list of requirements such as form factor, performance, functionality, power consumption, reliability, and cost.

Almost all of the components we choose will be sourced from third parties. Seldom (if ever) these days is there … Read More → "System Delta Sigma Delta"

Would it be possible to post a link to the Microsemi DAC paper? I did manage to find this - it has a table that mentions 56x https://www.codasip.com/2017/07/13/microsemi-and-codasips-presentation-at-dac-2017/ It looks like they are mentioning the improvement any baseline RISC (in their table they are comparing with ...

will be happy to spend the time to spread the fever ... won't try though with a reply I will mention one very tangible difference (but by no means the most important difference) between risc-v and ARM or x86 ... unless you buy an architectural license, you cannot change the ARM instruction ...

"ARM users have the choice of 100+ different vendors (it seems), all of which make chips that are totally 100% compliant with the ARM architecture standard" is not an accurate statement to my point. You are confusing the IC manufacturer/supplier of off-the-shelf components with the IP vendor who enables ASIC/SoC ...

It depends on your definition of "truly portable embedded software" Jim. Most embedded software is written in C and C++. These languages care not what the underlying ISA is. My observation on the ARM ecosystem is that, yes, there is a bunch of software out there but no two ARM ...

Your point is well made, but I still don't get it. ARM users have the choice of 100+ different vendors (it seems), all of which make chips that are totally 100% compliant with the ARM architecture standard. Same goes for MIPS-compatible processors, or SPARC processors, et al. The fact that ARM (or ...

I don't think it is about "open source processors" - it's about an "open STANDARD" called RISC-V. A good comparison is Verilog ... it is an open standard maintained by the IEEE and there are free open source Verilog simulators available. But companies designing ASICs and SoCs use PROPRIETARY Verilog simulators ...

Recall for a moment a scene—you’ve probably witnessed something like it at trade shows or on video dozens of times. A robot arm moves purposefully from its rest position. It swoops down on an object—a sphere, say—plucks it up, holds it aloft, replaces it, ...
