What is UBWC compression?

UBWC is a unique predictive bandwith compression scheme that improves effective throughput to system memory. By minimizing the bandwidth of data, significant power savings can be achieved. UBWC works across many components in Snapdragon processors including GPU, Display, Video, and Camera.

What is UBWC for camera?

1, compression and/or decompression may be performed via universal bandwidth compression/decompression (UBWC). UBWC compresses graphical buffers, such as GPU, video, and/or camera buffers.

What is universal bandwidth compression (ubwc)?

Universal bandwidth compression (UBWC) is supported by all A5x GPUs. UBWC is a unique predictive bandwith compression scheme that improves effective throughput to system memory. By minimizing the bandwidth of data, significant power savings can be achieved.

What is the compression ratio?

The compression ratio is the ratio between two elements: the gas volume in the cylinder with the piston at its highest point (top dead center of the stroke, TDC), and the gas volume with the piston at its lowest point (bottom dead center of the stroke, BDC). There are two ways of calculating the compression ratio for an engine.

What is ubwc in Snapdragon processors?

UBWC is a unique predictive bandwith compression scheme that improves effective throughput to system memory. By minimizing the bandwidth of data, significant power savings can be achieved. UBWC works across many components in Snapdragon processors including GPU, Display, Video, and Camera.

How do you find the compression ratio of a piston?

Working it out. To find the compression ratio (CR) you divide the total swept volume with the total compressed volume. This is how you find out what these totals are: Swept volume = chamber volume + piston volume + gasket volume + clearance volume + cylinder volume.
