In this paper, we present a UART-USB interface converter design based on FPGA, which implements asynchronous serial communication protocol and USB protocols conversion. Design is implied by Hardware Description Language using modular design, it can be integrated into different SoC system. After Modelsim functional simulation and FPGA simulation with two computers, we verify the feasibility of the...
The commercial embedded microprocessor requires to be authorized, which increases the cost of the chip. The free embedded microprocessor soft-core is of poor portability, which causes difficulty on system design. In order to solve the above problems, this paper introduces an improved IP core base on ARMv4 instruction set. With an independent architecture, the IP core possesses good portability and...
A high-performance deblocking filter for AVS HDTV application is proposed in this paper. Optimized filtering order and effective filtering process are applied to improve the system efficiency. Parallel processing of filtering operations, data reading, caching, transposing and writing is realized, which facilitates filtering operation while reducing temporary data storage. With data caching/transposing...
A new FPGA-based implementation scheme of the AES-128 (Advanced Encryption Standard, with 128-bit key) encryption algorithm is proposed in this paper. For maintaining the speed of encryption, the pipelining technology is applied and the mode of data transmission is modified in this design so that the chip size can be reduced. The 128-bit plaintext and the 128-bit initial key, as well as the 128-bit...
Asynchronous serial communication is widely used in computer communication. A method based on TL16C752B is introduced in this paper in order to resolve the problem that DSP6713B doesn't have its own asynchronous serial port. In this scheme, serial port expansion chip TL16C752B produced by TI is used to solve the problems of TL16C752B driving and achieve hardware connection between PC and DSP6713B...
