Configuration of programmable integrated circuits

摘要

Approaches for configuring programmable resources of a programmable IC are disclosed. A first set of configuration data is loaded using a configuration port of the programmable IC, which also includes input/output (I/O) ports. Programmable resources are configured according to the first set of configuration data to implement a master data link circuit and at least one slave data link circuit. The master data link circuit includes a hardwired communication circuit, and a set of the programmable resources arranged to form a communication control circuit configured to control the communication circuit to provide a data link for communicating data via one of the I/O ports. A second set of configuration data is loaded using the master data link circuit. Programmable resources of the programmable IC are configured according to the second set of configuration data to implement a logic circuit configured to communicate data via the slave data link circuit.
