Xilinx Announces RFSoCs

CQ CQ CQ - Calling CQ. This is 5G calling...

We’ve all heard it. 5G is coming. Maybe not soon, but as soon as we can get all those pesky technical issues worked out. Which pesky technical issues would those be? Glad you asked. It turns out that cramming a previously unfathomable amount of bandwidth over an unprecedented number of individual connections into each and every cell tower using millimeter wavelengths and 2 dimensional massive multiple-input multiple-output (MIMO) antenna arrays - and doing all of that within acceptable power and footprint constraints - is a really tough problem. Actually, it’s a LOT of really tough problems.  Read More

Safety and Security Conference

posted by Dick Selwood

With the growth of the IoT there is increased interest in the overlapping areas of safety and security. There is already a lot of knowledge on these issues and this has been shared by the IET's International System Safety and Cyber Security Conference. The eleventh version of this conference is running from 11—13 October 2016 in London. (14-Sep)

A More Secure Time Server

posted by Bryon Moyer

Time servers allow us to track multiple events from different systems and networks with a consistent time base. But an evildoer can flood such servers with requests, causing crashes. Microsemi has released a new time server that addresses this vulnerability. (13-Jan)

CyrilJ,

You're links are broken.

Also, Microsemi's THREE separate software suites are INCONSISTENT with Linux support.

What is FAR worse?

An 8-way time division multiplexor to "fairly share" memory between 6 processors and 2 DMA channels -- no priority accesses to starve another channel, no contention based allocations, just straight channel 1 gets only time slot 1, ch…

Now you might say that no one would be that stupid as to pack all accessed data into a single subchannel. With the number of sub-channels being 2^n (where n is 1, 2 or 3), it's also pretty likely that the underlying data structure to be processed will hav…

@Karl -- sure multiple banks/channels can offer concurrent read/write, or even multiply sourced reads/write -- but each channel still has the native single access or burst fill performance timings.

Now look at the last three figures above, where Cadenc…
