In almost every aspect, CPUs and FPGAs are radically different devices. And yet, they often compete for some of the same embedded system tasks. Choosing the best approach depends not only on the capabilities of each device, but also on the often disparate expertise of engineers promoting their respective development methodologies.
To make matters even more complicated, SoC (system-on-chip) technology now combines CPUs and FPGAs within the same device. Here, efficient interoperability becomes essential to meet stringent realtime performance levels. This article presents these challenges along with some strategies for developing successful solutions.
New generations of FPGAs provide superior processing performance and I/O bandwidth

Q&A with Pentek
Q: How do I select the correct Talon analog signal recorder?
The maximum sample rate of the A/D converter is listed in the main description of every Talon analog signal recorder. For example, the Model 2746 200 MS/s RF/IF Rugged Rackmount Recorder provides A/Ds with a maximum sample rate of 200 MHz. This sample rate dictates the maximum bandwidth signal that this recorder can accurately sample and record.
In the case of a 200 MHz A/D, we know that the maximum signal bandwidth that can be captured is 0.8 x fs/2, assuming a usersupplied 80% anti-aliasing filter. This means that this A/D can capture signals that are 80 MHz wide. A 3.6 GHz A/D product can capture signals that are 1440 MHz wide, assuming the same 80% filter.
Q: What signal types do the Talon digital signal recorders support?
A: Talon digital signal recorders include support for serial FPDP, Gigabit Ethernet, 10 Gigabit Ethernet, 40 Gigabit Ethernet, and LVDS.
