What is the bandwidth between Hailo-10H and DDR4?

Hey @XUBIN_GUO ,

Just to clarify - the Hailo-10H doesn’t actually use DDR4. It’s designed to work with LPDDR4 and LPDDR4x memory instead.

The memory interface runs at speeds up to 4266 MT/s with a 32-bit data bus (using 2 channels in lock-step mode).

So you’re looking at around 17 GB/s as the maximum theoretical bandwidth between the Hailo-10H and its LPDDR4/4x memory.

Keep in mind though - that’s the theoretical peak. In real-world usage, you’ll probably see somewhat lower numbers due to protocol overhead and various implementation factors.

Hope that helps clear things up!
