Does Mali-200 have hardware to implement bitblit?

Applies to: Mali-200


No, it does not. Instead, Mali200 would use textures to perform bitblit functionality. When doing bitblits Mali200 will be limited by available bandwidth so the performance should be similar to a dedicated hardware blitter.

If no blending is done, proper use of depth buffer and draw order will ensure that entirely
covered parts of the target buffer are never read in. Also, Mali200 has the ability to only write
back those parts of the frame buffer that have actually been rendered to, so for some use cases
(fully opaque bitblit) it is not required to use 2 textures.
