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
In fact KitKat advocates low-power always-on functionality, and this is essential for contextual-awareness. Always-on functionality is saving battery life, which seems to be weird at first: if your phone is always-on you would expect it to consume much power… But always-on goes together with screen-off (the screen is a high… Read More
In recent times semiconductor companies have revealed their intentions to license their in-house processor architectures for the first time – IBM want to license their Power CPU architecture, nVidia to license their GPU architecture. Most recently, a rumor has surfed: Qualcomm will license their DSP architecture. We should… 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
Smartphone shipment explosion and continuous growth is attracting always more OEM and chip makers, this is not really surprising, as the wireless market can be identified as the faster growing, and larger electronic segment ever seen. On such a mass market, the real question is “how to differentiate?” Apple is unique; just trying… 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
Until recently, talking about smartphone incredible shipment growth was understood as shipments of A5 iPhone or Galaxy Note, and this was true. Devices priced at $500 or more are shipping like baguette in Paris, but this fact is only true in Europe, Korea, Japan or USA. Does that means that people living populated countries like… Read More
Once upon a time, ASIC designers involved in Processor design, like I was, for the first time in 1987 for Thomson CSF and again in 1994 for Texas Instruments, at that time supporting height (8) ASIC designed by another French company, the Advanced Computer Research Institute (ACRI), had to re-invent the wheel almost every day. When… Read More
