 hopefully completed by Fall 2022.
  - Given that POWER CPUs do not have GPUs, RaptorCS
 would like the LibreSOC to be able function as a
-GPU in PCIE slave mode.
+discrete GPU in PCIE slave mode for POWER9 CPUs.
  - Lastly, RaptorCS would like to manufacture single
 board computers.
 
 ## Devices
  - 4 Core POWER CPU
- - SimpleV GPU
- - PCIE Slave controller(RaptorCS wants to use LibreSOC as a GPU on their POWER mobos)
+ - SimpleV Capability and GPU Instructions
  - IOMMU
  - Coherent Accelerator Processor Proxy (CAPP) functional unit
- - PCIE host Controller
+ - PCIe host Controller
+ - PCIe Slave controller(RaptorCS wants to use LibreSOC as a GPU on their POWER mobos)
+ - BMC - enables LibreSOC to become a discrete GPU with video output and ethernet.
+ - RGB/TTL framebuffer VGA/LCD PHY from Richard Herveille, RoaLogic.
