they also have a huge downside. 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.
Instead of using VHDL or Verilog to configure these logic primitives, CLB is programmed with a GUI-based SysConfig tool and function calls. Since the configuration method is different, the CLB is technically not a CPLD or FPGA, but it can be used to achieve identical results. The CLB holds...
most of the stored charge remains where it is, intact. A thinner bottom oxide can be used compared to the floating gate technology, and it can be programmed with lower programming voltages (~7.5 V) and smaller charge pumps. Fewer transistors are required with SONOS than wit...
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 ...
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 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...
This "distributed" business is easier to appreciate by looking at an example. Here's a schematic implementation of a 1D convolution on an FPGA – you convolve a long vector v with an N-coefficient filter f, computing, at every i, f0*v[i] + f1*v[i-1] + f2*v[i-2] + ... + ...
In many applications, they are a viable alternative for what otherwise would have been an ASIC-based solution. Like the original PLDs, there are FPGAs that only can be programmed once. These so-called one-time-programmable devices have the advantage of working from the instant the power is ...
The TPS6508640 is a variant of the TPS65086x device, which has default sequencing and voltage settings programmed to the requirements of the Xilinx UltraScale+ ZU9EG. This device has three DC/DC controllers driving an external dual field-effect transistor (FET). Selecting the size of the FET...
