Abstract:
1. A method for configuring a plurality of programmable logic devices connected to a local data bus from a single memory device comprising the steps of: communicating by a microprocessor connected to the local data bus through a communication port to which the microprocessor is directly connected; signaling a reset line on all of the programmable logic devices; selecting one of the programmable logic devices; toggling a program reset line on the selected programmable logic device; transmitting an initialization signal from the selected programmable logic device to the microprocessor; determining the status of the selected programmable logic device from the initialization signal; downloading a configuration from the single memory device connected to the microprocessor to the selected programmable logic device if there is no fault; and selecting a second one of the programmable logic devices and performing the steps of toggling, transmitting, determining, and downloading on the second selected programmable logic device.
