# Specs for 2022 SOC
+## Applications
+
+ - We are providing open source drivers for the GPU,
+hopefully completed by Fall 2022.
+ - Given that POWER CPUs do not have GPUs, RaptorCS
+would like the LibreSOC to be able function as a
+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
- - BMC
+ - SimpleV Capability and GPU Instructions
- IOMMU
- Coherent Accelerator Processor Proxy (CAPP) functional unit
- - PCIE Controller
- - places packets on SERDES PCIE lanes
- - recovers clock and detects skew
+ - 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.
