Texture decompression is the point for mobile GPUs

Texture decompression is the point for mobile GPUs
by Don Dingee on 09-18-2013 at 9:00 pm

In the first post of this series, we named the popular methods for texture compression in OpenGL ES, particularly Imagination Technologies PVRTC on all Apple and many Android mobile devices. Now, let’s explore what texture compression involves, what PVRTC does, and how it differs from other approaches.… Read More


How Do You Do Computational Photography at HD Video Rates?

How Do You Do Computational Photography at HD Video Rates?
by Paul McLellan on 09-18-2013 at 2:22 pm

Increasingly, a GPU is misnamed as a “graphics” processing unit. They are really specialized architecture highly parallel compute engines. You can use these compute engines for graphics, of course, but people are inventive and find ways of using GPUs for other tasks that can take advantage of the highly parallel… Read More


TSMC’s 16FinFET and 3D IC Reference Flows

TSMC’s 16FinFET and 3D IC Reference Flows
by Paul McLellan on 09-17-2013 at 2:01 am

Today TSMC announced three reference flows that they have been working on along with various EDA vendors (and ARM and perhaps other IP suppliers). The three new flows are:

  • 16FinFET Digital Reference Flow. Obviously this has full support for non-planar FinFET transistors including extraction, quantized pitch placement, low-vdd

Sidense and TSMC Processes

Sidense and TSMC Processes
by Paul McLellan on 09-14-2013 at 2:21 pm

I’ve written before about the basic capabilities of Sidense’s single transistor one-time programmable memory products (1T-OTP). Just to summarize, it is an anti-fuse device that works by permanently rupturing the gate oxide under the bit-cells storage transistor, something that is obviously irreversible.… Read More

by Eric Esteve on 09-09-2013 at 9:13 am

If you have ever send a Request For Quotation (RFQ) for an ASIC including processor IP core, memories, Interfaces IP like PCIe, SATA or USB and Analog function like Analog to Digital Converter (ADC) or Digital to Analog Converter (DAC), you have discovered, like I did a couple of years ago, that these Analog functions may be the key… Read More


Base Stations Move Away From Fixed Architecture DSP

Base Stations Move Away From Fixed Architecture DSP
by Paul McLellan on 09-06-2013 at 1:59 pm

Handsets moved away from fixed architecture DSP some time ago, driven by two main factors. Fixed architecture DSP consumed too much power to get good battery life in the smart-phone era, but the consumer air interface was changing fast: W-CDMA, HSPA, WiMax, 3G, LTE (which is actually a whole ‘spectrum’ of different… Read More


Ecosystem: ARM versus Intel

Ecosystem: ARM versus Intel
by Daniel Nenni on 09-05-2013 at 2:45 pm

Ecosystem is everything when it comes to modern semiconductor design, especially if it is mobile. The fabless semiconductor industry has been all about ecosystem since the beginning and that is why we hold supercomputers in our hands today, believe it. After the invention of the transistor in 1947, and the invention of the integrated… Read More


Did you miss Cadence’s MemCon?

Did you miss Cadence’s MemCon?
by Eric Esteve on 09-05-2013 at 4:42 am

That’s too bad, as you have missed latest news about the Hybrid Memory Cube (presentation by Micron), Wide I/O 2 standard, as well as other standards like LPDDR4, eMMC 5.0, and LRDIMM,the good news is that you may find all these presentations on MemCon proceedings web site.
I first had a look at Richard Goering excellent blog: wideI/ORead More


Must See SoC IP!

Must See SoC IP!
by Daniel Nenni on 09-02-2013 at 5:30 pm


IP is the center of the semiconductor universe and nobody knows this better than Design and Reuse. The D&R website was launched in 1997 targeting the emerging commercial semiconductor IP market. Today, with more than 15,000 IP/SOC product descriptions updated daily, D&R is the #1 IP site matching customer requirements… Read More


OTP Memory to Build Smarter Power Management

OTP Memory to Build Smarter Power Management
by Paul McLellan on 08-29-2013 at 11:20 pm

All chips have critical power management requirements, often with multiple supply voltages. Digital power management ICs (PMICs) are commonplace to convert unregulated voltages from batteries and noisy power supplies to fully regulated accurate power to keep even the most sensitive chips performing.

Powervation is a company… Read More
