摘要：A programmable switch (734) for a field programmable gate array (FPGA)
allows a user to reconfigure or partly reconfigure the FPGA from within the FPGA, allows
an addressable configuration memory to be addressed through a set of pins (17) for
configuration and through user logic for reconfiguration. The same pins (17) can be used
for both configuration and user logic. Also signals such as chip enable and other control
signals can be modified by user logic before performing their function so that chips
external to the FPGA can be eliminated. Upon power-up of the chip, each programmable
switch (734) connects its pad to the programming logic which programs configuration
memory, so that the programming logic can receive instructions from an external source
and control programming of the core logic of the chip. The configuration memory
programs not only the internal circuitry accessed by the user but also the programmable
switch (734) itself. Thus, as configuration proceeds, or after configuration is completed,
the programmable switch can be reconfigured to connect internal portions of the FPGA
user logic to parts of the configuration memory which were initially loaded from external
pins.
