Abstract

A system for maintaining reconfigurable partitions in an integrated device includes a first buffer having channels that store configuration data and a mask. The system also includes first decompression circuitry having a second buffer coupled to the first buffer that stores the configuration data and second decompression circuitry having a third buffer coupled to the first buffer that stores the mask. The system also includes partition maintenance circuitry that applies the mask to the configuration data after the first decompression circuitry has decompressed the configuration data and the second decompression circuitry has decompressed the mask.

A system for maintaining reconfigurable partitions in an integrated device comprising:

a first buffer comprising:
a first channel configured to store at least a first portion of configuration data;
a second channel configured to store at least a first portion of a mask;
first decompression circuitry comprising a second buffer coupled to the first buffer, wherein the second buffer is configured to store at least a second portion of the configuration data, wherein the first decompression circuitry is configured to decompress at least the second portion of the configuration data;
second decompression circuitry comprising a third buffer coupled to the first buffer, wherein the third buffer is configured to store at least a second portion of the mask, wherein the second decompression circuitry is configured to decompress at least the second portion of the mask;
and
partition maintenance circuitry configured to apply at least the second portion of the mask to at least the second portion of the configuration data after the first decompression circuitry has decompressed at least the second portion of the configuration data and the second decompression circuitry has decompressed at least the second portion of the mask.

An integrated circuit comprising:

first decompression circuitry configured to decompress at least a portion of configuration data, wherein the first decompression circuitry comprises a first buffer configured to store at least the portion of the configuration data;
second decompression circuitry configured to decompress at least a portion of a mask, wherein the second decompression circuitry comprises a second buffer configured to store at least the portion of the mask;
and
partition maintenance circuitry configured to apply at least the portion of the mask to at least the portion of the configuration data after the first decompression circuitry has decompressed at least the portion of the configuration data and the second decompression circuitry has decompressed at least the portion of the mask by:
performing an AND operation between at least the portion of the configuration data and at least the portion of the mask when the configuration data is associated with configuration random access memory data;
performing an XOR operation between at least the portion of the configuration data and at least the portion of the mask when the configuration data is associated with embedded random access memory data;
and
performing an XOR operation between at least the portion of the configuration data and at least the portion of the mask when the configuration data is associated with a command.
