Every time you cycle power to an FPGA, the SRAMs must be programmed. Think about that. Every time your FPGA-based product is powered up, the SRAM inside the FPGA must once again be reprogrammed. This generally takes the form of a small, reprogrammable nonvolatile memory, such as an ...
What is the Difference Between an Oscilloscope and a Digitizer? If you require more customizability than an oscilloscope, such as in-line FPGA processing, a digitizer may be a better fit for your application than an oscilloscope. For example, FlexRIO digitizers also feature high-performance analo...
FPGA Share The FPGA Section The words FPGA (Field Programmable Gate Array) and CPLD (Complex Programmable Logic Device) are everywhere nowadays. Not just for systems that actually need to be re-programmed in the field, but for any application that can't justify the up-front expense of an AS...
An audience member asked, “How can hardened NOCs between different hardened peripherals and internal logic gates affect the fastness of internal data paths which FPGA was lacking from the last two decades?” Jeff Yeah, and that that’s a detailed hardware question and it is a problem. You ...
Look-Up Tables (LUTs) are a key element of FPGAs that allow it to behave as “reconfigurable hardware”. Depending on the the size (number of inputs and outputs) of a LUT, some set of logic functions can be programmed as part of a design. Understanding how this is possible requires ...
Multiple trends are sending FPGAs down two distinct development paths. On one path, FPGAs are being optimized primarily to accelerate data center workloads. The data center focus is the next holy grail that the larger vendors are laser-focused on. On another development path, ...
An unencrypted bitstream can be loaded to configure the device even when a device holds an encryption key, given that POR or PROG asserted first clearing out the configuration memory. Note that once the FUSE_CNTL[0] bit is programmed, only bitstreams encrypted with the eFUSE key can be used...
I'm certain that this is a software issue and not a hardware issue as previsouly explained: Disable some USB ports in software, effectively removing some FPGAs visible to jtagd. The remaining FPGAs could then be repeatedly programmed successfully without and reported erro...
Then, the descriptor table is programmed to determine the transfer. The PCIe IP core's FIFO in the FPGA retrieves the descriptors from the software memory and performs the transfer according to the descriptors. Finally, an MSI interrupt is sent to the software to indicate the completion of ...
CompactRIO is a programmable control and monitoring system with a multi-core processor, real-time operating system, programmable FPGA, and compatibility with all C Series modules from NI and 3rd party companies. CompactRIO lets domain experts build embedded I/O controllers and monitoring systems to ...
