Which FPGA coprocessors are used for research sensor nodes?
FPGA coprocessors for research sensor nodes. Finally, two high-end (Virtex) FPGAs were used. In a Virtex-5 is utilized in order to implement the Loeffler DCT running at 100 MHz.
Why are FPGAs used as a coprocessor?
However, thanks to the high-speed embedded resources included in the FPGA such as DSP slices and fast memories, they are now also utilized for algorithm acceleration either as coprocessors or standalone systems, i.e., System-On-Chips (SoCs). Moreover, several vendors reserve space in the FPGAs to custom soft hard-IP (HIPs) processors.
What are FPGAs used for?
In the past, FPGAs have been mainly used in signal processing and network packet analysis . However, thanks to the high-speed embedded resources included in the FPGA such as DSP slices and fast memories, they are now also utilized for algorithm acceleration either as coprocessors or standalone systems, i.e., System-On-Chips (SoCs).
Which FPGA is best for reducing power consumption?
According to Table 7, the best results are produced using the IGLOO FPGA, i.e., [71, 72], where the power reduction implementing an FFT and image processing tasks was 30 and 13 times smaller respectively. Moreover, the authors of the PowWow sensor node measured the power consumption of the CRC32 algorithm in both microcontroller and FPGA .
What is a soft start FPGA?
Th is is when FPGAs initialize the internal logic blocks to valid operating states. Using soft-start is highly recommended, even if not specifi ed by the FPGA manufacturer. Slowly ramping the input voltage reduces the inrush currents seen in some FPGAs.
How does a FPGA wake up a microcontroller?
If a valid frame is received, the FPGA wakes up the microcontroller. According to the authors, the main tasks are carried out by the FPGA since its power consumption is reduced in comparison to the MSP430. Finally, a DC/DC converter is used to perform Dynamic Voltage Scaling (DVS) on both the FPGA and the microcontroller.
