   3 ## Applications
   4
   5  - We are providing open source drivers for the GPU,
   6 hopefully completed by Fall 2022.
   7  - Given that POWER CPUs do not have GPUs, RaptorCS
   8 would like the LibreSOC to be able function as a
   9 discrete GPU in PCIE slave mode for POWER9 CPUs.
  10  - Lastly, RaptorCS would like to manufacture single
  11 board computers.

  13 ## Devices
  14  - 4 Core POWER CPU
  15  - SimpleV GPU
  16  - IOMMU
  17  - Coherent Accelerator Processor Proxy (CAPP) functional unit
  18  - PCIE host Controller
  19  - PCIE Slave controller(RaptorCS also wants to use LibreSOC as a GPU on their POWER mobos)
  20  - BMC - enables LibreSOC to become a discrete GPU with video output and ethernet.

  24 ### Advanced
  25
  26  - SERDES - 10rx, 14tx
  27    - 4tx, 4rx for [OMI(DDR4](https://openpowerfoundation.org/wp-content/uploads/2018/10/Jeff-Steuchli.OpenCAPI-OPS-OMI.pdf) on top of SERDES with OpenCAPI protocol) @5GHz
  28    - 2tx, 2rx for ethernet
  29    - 4tx, 4rx for PCIE and other CAPI devices
  30    - 3tx for HDMI
  31  - [OpenFSI](https://openpowerfoundation.org/?resource_lib=field-replaceable-unit-fru-service-interface-fsi-openfsi-specification) instead of JTAG
  32    - [Raptor HDL](https://gitlab.raptorengineering.com/raptor-engineering-public/lpc-spi-bridge-fpga)
  33    - [Raptor Libsigrok](https://gitlab.raptorengineering.com/raptor-engineering-public/dsview/-/tree/master/libsigrokdecode4DSL/decoders/fsi)
  34  - USB 2.0 - [Luna USB](https://github.com/greatscottgadgets/luna)
  35 with [USB3300 PHY](https://www.microchip.com/wwwproducts/en/USB3300#datasheet-toggle) (Tested max at 333MB/s with Luna on ECP5)
