  • Programmable device configuration memory system
    Patent number: 11386009
    Abstract: An example configuration system for a programmable device includes: a configuration memory read/write unit configured to receive configuration data for storage in a configuration memory of the programmable device, the configuration memory comprising a plurality of frames; a plurality of configuration memory read/write controllers coupled to the configuration memory read/write unit; a plurality of fabric sub-regions (FSRs) respectively coupled to the plurality of configuration memory read/write controllers, each FSR including a pipeline of memory cells of the configuration memory disposed between buffers and a configuration memory read/write pipeline unit coupled between the pipeline and a next one of the plurality of FSRs.
    Type: Grant
    Filed: October 31, 2019

  • Run length compression and decompression using an alternative value for single occurrences of a run value
    Patent number: 10305511
    Abstract: Decompressing a data set includes inputting data units to a decompression circuit and comparing each input data unit to a run value and to a substitute value. In response to the data unit being not equal to the run value or the substitute value, the decompression circuit outputs the value of the input data unit; in response to the input data unit having the run value and a succeeding data unit having a value N not equal to zero or one, the decompression circuit outputs multiple data units having the run value based on the value N; in response to input data unit having the substitute value, the decompression circuit outputs one data unit having the run value; and in response to one input data unit having the run value and a succeeding data unit equal to zero or one, the decompression circuit outputs one data unit of the substitute value.
