可编程逻辑 XAPP440 - Xilinx CPLD的上电性能

Applying power to a standard logic chip, SRAM, or EPROM, usually results in output pinstracking the applied voltage as it rises. Programmable logic attempts to emulate that behavior,but physics forbids perfect emulation, due to the device programmability. It requires care tospecify the pin behavio ...

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to ...

单片机开发 Wireless range extenders or wireless repeaters can extend the range of an existing wireless network.

Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected thr ...

技术资料 shift_register_ram

Altera provides a RAM-based shift register megafunction called ALTSHIFT_TAPS that contains additional features not found in a conventional shift register. Traditional shift registers implemented with standard flip-flops use many logic cells for large shift registers. The ALTSHIFT_TAPS megafunction i ...
