Title: GPU. Lesson 4. GPU Memory Architecture Essentials

1. GPU memory hierarchy impacts data access speed and efficiency.

2. Registers are high-speed storage located within each processing core.

3. Shared memory provides fast access for threads within a multiprocessor.

4. Global memory, or VRAM, stores large data accessible by all cores.

5. Texture memory optimizes specific data types like images in GPU tasks.

6. Constant memory stores data that doesn’t change during execution.

7. Caches like L1 and L2 reduce latency for frequently used data.

8. Latency is the delay in accessing data from a memory source.

9. Bandwidth measures the data transfer rate across memory levels.

10. Memory coalescing optimizes global memory access for multiple threads.

Technical Examples:

1. Registers and Shared Memory: Registers provide immediate data access, while shared memory facilitates collaboration among threads.

2. Texture and Constant Memory: Texture memory improves image processing; constant memory efficiently holds static data.

3. Memory Coalescing: Coalescing minimizes memory access delays by aligning multiple thread requests for optimal efficiency.
