When you first learn about digital logic, it probably seems like it is easy. You learn about AND and OR gates and figure that’s not very hard. However, going from a few basic gates to somethi… ...

From Gates To FPGA’s – Part 1: Basic Logic. 74 Comments . by: Bil Herd. May 28, 2015. Title: ... Most if not all of the standard logic blocks come in an inverted form also such as the NAND ...

Fig 3. FPGA: Basic Structure. The features of a logic block (called a Configurable Logic Block (CLB) by Xilinx) shown in figure 4 is based on look-up tables (LUTs) . A LUT is a small one bit wide ...

San Jose, Calif. – As the 90-nanometer technology node kicks in, chip vendors are finding they must abandon some time-tested principles to navigate the transition. Case in point: Xilinx Inc. and ...

While simple FPGAs offer the ability to implement only basic logic functions, more advanced FPGAs provide embedded RAMs, multipliers, and highly specialized IO structures. These embedded elements are ...

Today FPGA design and manufacture are cutting edge silicon technologies on a par with processors from Intel. In fact the high end FPGAs contain around 7 billion - that’s seven thousand, thousand, ...

Logic synthesis tools also allows for technology independent designs. Logic synthesis technology was commercialized around 2004, and since then it’s been part of the standard EDA tool chain for ASICs ...

Most of the newer FPGA architectures today have embedded multipliers or DSP blocks along with other resources like logic elements and memories. The availability of high-speed, optimized DSP blocks ...

Fig 1: Analog to digital converter basic block diagram: low frequency and high frequency options Low frequency/minimal logic ADC implementation description In the low frequency/minimal logic ...

One approach is to treat a block of FPGA logic as a piece of intellectual property (IP). Then, the suppliers can co-integrate the FPGA blocks with the custom circuitry and other IP blocks.
