Will Open-Source Processors Cause A Verification Shift?


While the promised flexibility of open source could have advantages and possibilities for processors and SoCs, where does the industry stand on verification approaches and methodologies from here? Single-source ISAs of the past relied on general industry verification technologies and methodologies, but open-source ISA-based processor users and adopters will need to review the verification flows... » read more

Week in Review: IoT, Security, Autos


Products/Services Rambus reports completing the sale of its Payments and Ticketing businesses to Visa for $75 million in cash. “With 30 years of experience pushing the envelope in semiconductor design, we look toward a future of continued innovation to carry on our mission of making data faster and safer,” Rambus President and CEO Luc Seraphin said in a statement. “Completing this transa... » read more

Open ISAs Gaining Traction


Open instruction set architectures are starting to gain a foothold, often in combination with other processors, as chipmakers begin to add more specialized compute elements and more flexibility into their designs. There are a number of these open ISAs available today, including Power, MIPS, and RISC-V, and there are a number of permutations and tools available for sale based on those archite... » read more

RISC-V Pros And Cons


Simpler, faster, lower-power hardware with a free, open, simple instruction set architecture? While it sounds too good to be true, efforts are underway to do just that with RISC-V, the instruction-set architecture (ISA) developed by UC Berkeley engineers and now administered by a foundation. It has been known for some time that with [getkc id="74" comment="Moore's Law"] not offering the same... » read more

Supporting CPUs Plus FPGAs (Part 3)


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

How Cache Coherency Impacts Power, Performance


As discussed in part one, one of the reasons cache coherency is becoming more important is the shared common memory resource in designs today. Various agents in the design want to access the data the fastest they can, putting pressure on the CPU complex to manage all of the requests. Until a generation ago, it was okay for the CPU to control that memory and have access to it, as well as be t... » read more

Will Open-Source Work For Chips?


Open source is getting a second look by the semiconductor industry, driven by the high cost of design at complex nodes along with fragmentation in end markets, which increasingly means that one size or approach no longer fits all. The open source movement, as we know it today, started in the 1980s with the launch of the GNU project, which was about the time the electronic design automation (... » read more

Will The Chip Work?


As the number of possible issues mount for integrating IP into complex chips, so does the focus on solving these issues. What becomes quickly apparent to anyone integrating multiple IP blocks is that one size doesn't fit all, either from an IP or a tools standpoint. There is no single solution because there is no single way of putting IP together. Each architecture is unique, and each brings... » read more

The Week In Review: Design/IoT


Tools Mentor Graphics rolled out a new version of its tool for transferring PCB designs into data for fabrication, assembly and test. The company also announced that its debug environment will support the UPF Low Power Successive Refinement Methodology. Deals Ansys and Cray are claiming the world's record for simulation by scaling 129,000 cores. That's about 4X the previous record.  Ansys... » read more

Leveraging Processor Extensibility To Build An Ultra Low-Power Embedded Subsystem


There is increasing demand for electronic devices to execute more functions while consuming less power and silicon area. To achieve this, systems instantiating multiple, heterogeneous processor cores optimized for low power and high performance are gaining popularity among design teams. In these systems, one or more deeply embedded processors execute a limited set of dedicated applications. The... » read more
