In what situations should constant memory be replaced with texture memory?

edit

Texture memory should be used when:

1. Memory access patterns are predictable and repetitive: Texture memory is optimized for repeated and patterned access, which makes it an ideal choice for applications that access the same data multiple times.

2. Data can be preprocessed: Texture memory is meant for preprocessed or partially preprocessed data, such as textures or lookup tables. If the data requires a significant amount of processing before being used, it may not be suitable for texture memory.

3. Data is read-only: Texture memory is optimized for read-only access. If the data needs to be changed frequently, it might not be the best fit for texture memory.

4. The data is two-dimensional: Texture memory is specifically designed to hold two-dimensional data like images, videos, and textures because it can efficiently interpolate values between pixels.

5. The data has limited precision: Due to its limited precision, texture memory may not be the best option for storing high-precision data like scientific simulations or high-end graphics.
