What is Xilinx SelectIO?
Xilinx provides an easy to use wizard to configure the SelectIO blocks in Xilinx FPGAs. The LogiCORE™ IP SelectIO™ Interface Wizard provides an intuitive customization GUI that helps users configure SelectIO blocks on Xilinx FPGAs to support their design requirements.
What is IOB Xilinx?
The IOB connects the I/O-pads to the ICN. These blocks can be configured as input, output or bidirectional blocks. The CLBs are configurable logic blocks consisting of two 16bit (and one 8bit) lookup table for logic functions and two flipflops for state storage.
What is ODDR Xilinx?
Introduction. This design element is a dedicated output register for use in transmitting double data rate (DDR) signals from FPGA devices. The ODDR interface with the FPGA fabric is not limited to opposite clock edges. It can be configured to present date from the FPGA fabric at the same clock edge.
What is an IOB in FPGA?
IOB (Input Output Block) is a programmable input and output unit, which is the interface between fpga and external circuits. Used to complete the driving and matching requirements for input/output signals under different electrical characteristics.
What is CLB FPGA?
A configurable logic block (CLB) is the basic repeating logic resource on an FPGA. When linked together by routing resources, the components in CLBs execute complex logic functions, implement memory functions, and synchronize code on the FPGA.
What is FPGA LUT?
The LUT in an FPGA holds a custom truth table, which is loaded when the chip is powered up. Think of the LUT as a small scratchpad RAM. The LUT inputs act as the address lines for a corresponding one-bit-wide RAM cell.
How many CLB are in a FPGA?
There are hundreds of similar logic block available onto the FPGA connected via routing resources. The purpose of these logic blocks is to implement combinational and sequential logic. There are three essential CLBs components: Flip-Flops.
What is a SerDes circuit?
A SerDes (Serializer/Deserializer) is an integrated circuit or device in use in high-speed communications that converts between serial data and parallel interfaces in either direction.
What are SerDes used for?
The primary utilization of SerDes is to facilitate data transmission over a single-line or a differential pair to mitigate the number of input pins, output pins, and interconnects. In summary, we utilize SerDes for the conversion of incoming parallel data into serial data.
How many LUTs are in a CLB?
In an effort to avoid getting lost before we really begin, here is a crude diagram illustrating this internal structure. And to itemize: one CLB = 2 slices, one slice = 4 LUTs + 8 FF. Therefore, one CLB = 8 LUTs + 16FF.
What is an LVDS interface?
The LVDS interface transmits data over four differential data pairs six or eight bits at a time. One example of a display that is connected through an LVDS interface is E70RA-HW520-C. This display is a 7.0” TFT with 1024×600 pixels and can display up to 16.7M colors.
What is LVDS (low-voltage differential signaling)?
Description LVDS (low-voltage differential signaling) is a high-speed, long-distance digital interface for serial communication (sending one bit at time) over two copper wires (differential) that are placed at 180 degrees from each other. This configuration reduces noise emission by making the noise more findable and filterable.
What is the difference between MIPI display serial interface and LVDS?
Specifically, the MIPI Display Serial Interface (DSI) technology is designed for display communication. LVDS is a technique that uses differential signaling at low voltages to transmit display data.
What are the disadvantages of LVDS over MCU interface?
Disadvantage is that controlling LCD is more complex, and requires more data wires than MCU interface. LVDS (Low-voltage differential signaling) is an electrical digital signaling standard that can run at very high speeds over inexpensive twisted-pair copper cables.
