Floating-point data compression

A computer system comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• receive data comprising a fractional number comprising an exponential component and a fractional component, the exponential component being represented by an exponential bit sequence, the fractional component being represented by a fractional bit sequence, wherein the data comprises image data comprising a plurality of tiles, a first tile of the plurality of tiles being represented at least in part by the fractional number;
• determine if the fractional component is within a threshold of 0 or 1;
• set the fractional component to 0 when the fractional component is within the threshold of 0 or 1;
• downscale the fractional bit sequence based on a difference between the exponential component and a second threshold;
• encode the data comprising to:
• determine a predictor value for the first tile;
• and
• calculate a residual for the first tile based on the fractional number and the predictor value;
• and
• transmit the encoded data.

A non-transitory computer readable medium having instructions stored thereon for encoding data, execution of the instructions by a computing system causing the computing system to carry out the steps of:

• receiving data comprising a fractional number comprising an exponential component and a fractional component, the exponential component being represented by an exponential bit sequence, the fractional component being represented by a fractional bit sequence, wherein the data comprises image data comprising a plurality of tiles, a first tile of the plurality of tiles being represented at least in part by the fractional number;
• determining if the fractional component is within a threshold of 0 or 1;
• setting the fractional component to 0 when the fractional component is within the threshold of 0 or 1;
• downscaling the fractional bit sequence based on a difference between the exponential component and a second threshold;
• encoding the data comprising:
• determining a predictor value for the first tile;
• and
• calculating a residual for the first tile based on the fractional number and the predictor value;
• and
• transmitting the encoded data.
