Abstract
A wireless programmable logic device contains a wireless component and a programmable logic component. A remote wireless host can be used to program the programmable logic device. Some product designs require multiple programmable logic devices. When wireless programmable logic devices are used in the design, all of them can receive data and commands from the host. As a result, the wireless host can control the order of configuration and the start time of these logic devices. There is no need to build glue logic for this purpose. Consequently, the efficiency in product design is improved. If there are problems in programming a programmable logic device, the host can log the failed operation in its memory. This information could be used to improve production flow.
Claims24
An integrated circuit communicating digital data with a remote host, said integrated circuit comprising:
- a wireless transceiver for receiving said digital data comprising a configuration bitstream from said remote host;
- a base band unit connected to said wireless transceiver to perform data processing operations on said digital data;
- and
- a programmable logic component and a programmable interconnect structure element connected to said base band unit, configuration bitstream being used to configure internal configuration memory cells for said programmable logic component and said programmable interconnect structure element, said configuration bitstream determining the functionality of said integrated circuit, wherein:
- said integrated circuit is a FPGA and said digital data is configuration bitstream data:
- and
- wherein said integrated circuit is not connected to a programmable read only via a wired connection.
A method for wireless communication between a remote host and a programmable logic device, comprising the steps of:
- receiving, by a target programmable logic device, a query transmitted by said host;
- receiving, by said target programmable logic device, a set of digital data comprising a configuration bitstream transmitted by said host, said configuration bitstream determining the functionality of said target programmable device;
- and
- initially configuring internal configuration memory cells for a configurable logic block of said target programmable device using at least a portion of said configuration bitstream. wherein said target programmable logic device is connected to a slave programmable logic device, said method further comprising a step of delivering at least a portion of said digital data to said slave programmable logic device.
