本白皮书探讨了在PCI Express的因素 技术可能会影响性能。它还 提供指导如何估算 的系统性能。(This white paper explores the factors in PCI Express technology may affect performance. It also provides guidance on how to estimate the system performance.)

Simple UART for FPGA is UART (Universal Asynchronous Receiver & Transmitter) controller for serial communication with an FPGA. The UART controller was implemented using VHDL 93 and is applicable to any FPGA. Simple UART for FPGA requires: 1 start bit, 8 data bits, 1 stop bit! The UART controller was simulated and tested in hardware.
