Method and apparatus for compression of graphics processing commands

A method for data processing, comprising:

• capturing a first graphics processing command including vertex data;
• constructing a data array having a plurality of data vectors from the vertex data;
• determining whether the data array is of a specific data type, the specific data type comprising an integer type and a float point type, where a difference between the value of each data element in a data array of the float point type and its rounded value is less than a threshold;
• in response to the data array being of the specific data type, determining whether a semantic property of the data array is color;
• and
• in response to the semantic property being color,
• determining a plurality of representative data vectors that are different from each other in the plurality of data vectors;
• constructing a palette array having a plurality of palette vectors each containing data elements of a corresponding one of the plurality of representative data vectors and a palette vector identifier;
• and
• generating a modified first graphics processing command by replacing the data array with the palette array and a sequence of palette vector identifiers, wherein a palette vector identifier in the sequence indicating one of the plurality of data vectors corresponding to one of the plurality of palette vectors with the same palette vector identifier.

A system for data processing, comprising:

• a first memory;
• and
• a first processor coupled to the first memory, the first processor to:
• capture a first graphics processing command including vertex data;
• construct a data array having a plurality of data vectors from the vertex data;
• determine whether the data array is of a specific data type, the specific data type comprising an integer type and a float point type, where a difference between the value of each data element in a data array of the float point type and its rounded value is less than a threshold;
• in response to the data array being of the specific data type, determine whether a semantic property of the data array is color;
• and
• in response to the semantic property being color,
• determine a plurality of representative data vectors that are different from each other in the plurality of data vectors;
• construct a palette array having a plurality of palette vectors each containing data elements of a corresponding one of the plurality of representative data vectors and a palette vector identifier;
• and
• generate a modified first graphics processing command by replacing the data array with the palette array and a sequence of palette vector identifiers, wherein a palette vector identifier in the sequence indicating one of the plurality of data vectors corresponding to one of the plurality of palette vectors with the same palette vector identifier.
