Programmable switch for FPGA input/output signals

摘要: A programmable switch for a field gate array (FPGA) allows user to reconfigure or partly the FPGA from within FPGA, an addressable configuration memory be addressed through set of pins and logic reconfiguration. The same can used both logic. Also signals such as chip enable other control modified by before performing their function so that chips external eliminated. Upon power-up chip, each connects its pad programming which programs memory, receive instructions source core chip. not only internal circuitry accessed but also itself. Thus proceeds, after is completed, reconfigured connect portions parts were initially loaded pins.
