Embedded FPGA – a New System-Level Programming Paradigm (WP006)

The current public debate on the future of the semiconductor industry has turned to discussions about a growing selection of technologies that focuses instead on new system architectures and better use of available silicon through new concepts in circuit, device, and packaging design. The emergence of embedded FPGA is, in fact, not only essential at this juncture of the microelectronics history, but also inevitable. To understand this, a review of the history of FPGA technology is in order.

Using FPGAs to Accelerate Data Centers (WP005)

With the technology industry at a crossroads — the effective repeal of Moore's Law  — data centers have become the sweet spot of the technology sector, showing healthy revenue growth and attracting new system solutions in both hardware and software. Unlike the ethereal promise of upcoming wonders from AI, robotics and the IoT, data center growth and innovation is happening in the here and now, with an even brighter future ahead the moment other nascent markets emerge from their chrysalis with killer apps of their own.

Routing Reset Signals on Speedcore eFPGAs (AN007)

In FPGA design, reset signals can sometimes have a significant effect on the overall quality of timing or routing results. Generally it is recommended to reduce the number of logic elements that need to be reset by taking advantage of initial values and coding in such a way that reset is only needed on a few end points.

Measuring Accurate Toggle Rates

When calculating dynamic power for a design, one input to any power estimation is the toggle rate of the signals. In most circumstances, the value used will be one of the industry standards of either 12.5% or 25% — values derived from a wide range of designs.

Device Binning Methodologies (AN005)

The manufacturing process for any silicon device inevitably has variations, whether those are in the thickness of a substrate or track, the purity of a conductor, position of the die on the wafer, or one of a myriad of many other physical effects.
