Ray tracing BVH unit
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 3
Fixed-function BVH traversal with ray-box and ray-triangle intersection tests and a traversal stack, serving shader ray queries.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | AXI4-Lite control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
Standards
- Khronos Vulkan 1.3 (VK_KHR_ray_query)
