The principle of Core I2C and the design of I2C IP core using FPGA technology
I2C (Inter Integrated Circuit) bidirectional two-wire serial bus is developed by Philips. The I2C bus is a multi-master bus that uses a serial data line (SDA) and a serial clock line (SCL) to communicate information on the bus. Each device has a unique identifying address and can act as either a transmitter or a receiver. […]
Advantages and disadvantages of FPGA technology, how to perform design verification
Once upon a time, to verify the logic design of an FPGA, you could compile, write, and then press the reset button on the evaluation board. However, with the increase of FPGA scale, this verification method, which Hitesh Patel, director of software product marketing at Xilinx, called “blow and go” (escape method), can no longer […]
Design of two-dimensional barcode recognition system based on SOPC technology based on FPGA solution
PDF in the two-dimensional barcode PDF417 is the abbreviation of Portable Data File. The storage capacity of each PDF code can be as high as 1 108 bytes, and it can be stored as 2 729 bytes if the number is compressed. As a new information storage and transmission technology, PDF417 has the advantages of […]
Design of Transmitting and Receiving Module Based on FPGA to Realize UTOPIA LEVEL2 Interface Timing
1 Introduction In the ADSL system, DSLAM (Digital Subscriber Access Multiplexer) completes the termination and routing of ATM. The model is divided into 4 layers, from top to bottom is divided into high layer, from AAL layer, ATM layer and physical layer. The high layer here refers to RFC1483 and above layers. The AAL layer […]
Realization of Timing Design of SpaeeWire Codec Receiver Based on FPGA Device and Libem Development Environment
introduction SpacewiTe is a high-speed, point-to-point, full-duplex serial bus network proposed by ESA in 2003 for space applications. Based on IEEE 1355-1995 and LVDS standards, it provides a general interface standard to simplify and standardize the interconnection between different devices, which plays an important role in solving the current lack of bus bandwidth in the […]
Design of Four-phase Absolute Phase Shift Keying Technology Modulation Circuit Based on FPGA
1 Introduction Quadrature Absolute Phase Shift Keying (QPSK) technology is widely used in digital communication systems due to its strong anti-interference performance, good bit error performance and high spectrum utilization. With the emergence of VLSI, the application of FPGA in digital communication system is becoming more and more extensive. At present, many methods to realize […]
A Design Methodology for Implementing Different Industrial Ethernet Protocols Using an FPGA-Based Platform
Industrial Ethernet refers to the use of Ethernet-based protocols to realize real-time and reliable communication in industrial automation and product mechanical control, and to realize a common platform through the Internet between the bottom controllers of the workshop, between workshops, and between workshops and offices. Since these protocols are implemented on the same IEEE 802.3 […]
Design of High-speed Mass Storage System Based on Logic Function of FPGA
introduction In measurement technology, a large number of digital images captured by high-speed digital cameras need high-speed, large-capacity image storage devices to be stored in real time and quickly. Using the traditional tape method to record data, its efficiency and security are not high; static memory is easy to read and write, but the stored […]
Design of Satellite Channel Simulator Based on FPGA Chip XC3S2000
1 Introduction The feasibility and quality of the services provided by the satellite mobile communication system are largely affected by the channel characteristics between the satellite and the mobile terminal. Investigating these effects requires experiments under certain propagation characteristics. Due to the limited conditions, it is impossible to carry out real-time field experiments, which are […]
