The global rollout of fourth-generation wireless (4G) infrastructure requires new architectural frameworks for RF devices with demands like high linearity. Integrated Device Technology (IDT) Inc. is confident that its high-performance RF solutions for high-bandwidth communications will open a new window of opportunity… Read More

Qualcomm Enters Server CPU Market
Fresh from the leaked memo that Intel is merging its mobile business into its PC client group, Qualcomm is going the other way and has confirmed that it is entering the ARM server CPU market, an announcement made at its analyst day earlier today.
This is a major trend that less than a month ago I reported from the Linley microprocessor… Read More
DSPs converging on software defined everything
In our fascination where architecture meets the ideas of Fourier, Nyquist, Reed, Shannon, and others, we almost missed the shift – most digital signal processing isn’t happening on a big piece of silicon called a DSP anymore.
It didn’t start out that way. General purpose CPUs, which can do almost anything given enough code, time,… Read More
How to Design an LTE Modem
Designing an LTE modem is an interesting case study in architectural and system level design because it is pretty much on the limit of what is possible in a current process node such as 28nm. I talked to Johannes Stahl of Synopsys about how you would accomplish this with the Synopsys suite of system level tools. He is the first to admit… Read More
CEVA and ARM Do LTE
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
Intel’s Q2 Conference Call
Yesterday was Intel’s Q2 conference call. I think that there are some interesting little pieces of information. The financials were what analysts expected although they did take down their guidance for the rest of the year. But that is never the interesting point of Intel conference calls (they almost always hit guidance).… Read More
Challenges of Implementing LTE
LTE (Long Term Evolution) is the true 4G standard for cellular and, over time, wireless internet. In fact it is several different standards with different levels of performance. LTE will eventually be the only technology used in cellular, voice will simply be Voice-over-IP (VoIP, the same technology that companies like Skype… Read More
A Brief History of Mobile: Generations 3 and 4
The early first generation analog standards all used a technique known as Frequency Division Multiple Access (FDMA). All this means is that each call was assigned its own frequency band in the radio spectrum. Since each band was only allocated to one phone, there was no interference between different calls. When a call finished… Read More
Smart mobile SoCs: Qualcomm
In the opener to this series, I alluded to a company designing their own approach, and it goes way beyond the graphics core in their solution. Qualcomm is unique in a holistic approach to a smart mobile device with their vertically integrated chipset, the Snapdragon S4.… Read More
LTE-Advanced Handsets for 4G
Due to a lot of somewhat aggressive marketing by carriers, you might think that 4G wireless is already here. After all, wasn’t 3G ages ago? But in fact true 4G handsets won’t really be available until 2015/6. But to make that schedule, first silicon needs to be available late this year or early next, to allow one or two … Read More
