Abstract
Programmable logic devices and techniques for programming and/or reconfiguring these devices are disclosed. For example, in accordance with an embodiment of the present invention, a programmable logic device is disclosed that incorporates flash memory and SRAM and includes multiple data ports for programming the flash memory and/or the SRAM.
Claims18
A programmable logic device comprising:
- volatile memory adapted to configure the programmable logic device based on configuration data stored by the volatile memory;
- non-volatile memory adapted to store configuration data;
- and
- a command decoder operable to control the transfer of configuration data from the non-volatile memory to the volatile memory and from the volatile memory to the non-volatile memory.
1 more element
A programmable logic device comprising:
- volatile memory adapted to configure the programmable logic device based on configuration data stored by the volatile memory;
- non-volatile memory adapted to store configuration data;
- and
- means for controlling the transfer of configuration data from the non-volatile memory to the volatile memory and from the volatile memory to the non-volatile memory.
1 more element
A method of configuring a programmable logic device, comprising:
- providing volatile memory within the programmable logic device adapted to configure the programmable logic device based on configuration data stored by the volatile memory;
- providing non-volatile memory within the programmable logic device adapted to store configuration data;
- transferring configuration data from an external configuration device to the volatile memory to configure the programmable logic device;
- and
- transferring the configuration data from the volatile memory to non-volatile memory to store the configuration data.
