I came across an interesting article by Will Strauss which is pretty much the history of DSP in communication chips. Having lived through the early part of the history while I was at VLSI Technology I found it especially interesting.
At VSLI, our first GSM (2G, i.e. digital not analog air interface) was a 5-chip chipset. The DSP functionality… Read More
Eyal Bergman of CEVA announced their latest core yesterday at the Linley Microprocessor Conference. It’s their 4th generation CEVA-XC solution, which is the core of their offering for wireless baseband. It builds on 3 previous generations of CEVA-XC’s that were mainly targeted toward handset applications. This… Read More
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
How do you benchmark a processor? It seems like it should be easy, just run some code and see how fast it is. Traditionally processors were indeed benchmarked by raw performance like GMACS, GFLOPS, memory bandwidth and so on. But in today’s world where systems have become very complex and applications very compute intensive, the… Read More
There is an intriguingly amorphous term in FPGA design circles lately: Quality of Results, or QoR. Fitting a design in an FPGA is just the start – is a design optimal in real estate, throughput, power consumption, and IP reuse? Paradoxically, as FPGAs get bigger and take on bigger signal processing problems, QoR has become a larger… Read More
Trying to trace DSP birth as a standard IC product, you come back to the early 80’s, when a certain Computer manufacturer named IBM has asked to a certain Semi-Conductor giant (at that time) named Texas Instruments if they could turn a lab concept, Digital Signal Processor, into a standard product that IBM could buy to TI, like they… Read More
If you have purchased a high-end cell-phone or tablet in the last couple of years it probably has LTE, although some carriers try and blur things by showing a symbol like 4G when you are in an area that has LTE despite the fact that your phone does not support it. Don’t you love cell-phone marketing? Talking of which, if a camel … Read More
I’m utterly amazed at how IC-based products are improving our quality of life by implantable devices. The modern day pacemaker has given people added years of life by electrically stimulating the heart. A privately-held company called NeuroPace was founded in Mountain View, California to treat epilepsy by using responsive… Read More
Video is a huge growing area and advanced imaging applications are becoming ubiquitous. By “advanced” I mean more than just things like cameras in your smartphone. There is lots more coming, from high-dynamic range (HDR) photography, gesture recognition, more and more intelligent video in cars to keep us safe, … Read More
Yesterday, I clicked “like” on a LinkedIn post with the title “TI Cuts 1,700 Jobs”. Today, I read the analysis and pulled out Social Distortion’s “Still Alive” for inspiration. I’ve been through this more than once. For them it’s not like-worthy, and I feel their sting.
The part of the post I liked was the comment: “This is good for … Read More
