[> Intro

|
|
|
---------
|
|
|
|
|
LiteDRAM provides a small footprint and configurable DRAM core.
|
|
|
|
|
|
|
|
|
|
LiteDRAM is part of LiteX libraries whose aims are to lower entry level of
|
|
|
|
|
complex FPGA cores by providing simple, elegant and efficient implementations
|
|
|
|
|
ofcomponents used in today's SoC such as Ethernet, SATA, PCIe, SDRAM Controller...
|
|
|
|
|
|
|
|
|
|
The core uses simple and specific streaming buses and will provides in the future
|
|
|
|
|
adapters to use standardized AXI or Avalon-ST streaming buses.
|
|
|
|
|
|
|
|
|
|
Since Python is used to describe the HDL, the core is highly and easily
|
|
|
|
|
configurable.
|
|
|
|
|
|
|
|
|
|
LiteDRAM uses technologies developed in partnership with M-Labs Ltd:
|
|
|
|
|
- Migen enables generating HDL with Python in an efficient way.
|
|
|
|
|
- MiSoC provides the basic blocks to build a powerful and small footprint SoC.
|
|
|
|
|
|
2015-09-15 02:33:53 -04:00
|
|
|
LiteDRAM can be used as a Migen/MiSoC library (by simply installing it
|
2015-02-22 12:19:05 -05:00
|
|
|
with the provided setup.py) or can be integrated with your standard design flow
|
|
|
|
|
by generating the verilog rtl that you will use as a standard core.

LiteDRAM is released under the very permissive two-clause BSD license. Under
|
|
|
|
|
the terms of this license, you are authorized to use LiteDRAM for closed-source
|
|
|
|
|
proprietary designs.
|
|
|
|
|
Even though we do not require you to do so, those things are awesome, so please
|
|
|
|
|
do them if possible:
|
|
|
|
|
- tell us that you are using LiteDRAM
|
|
|
|
|
- cite LiteDRAM in publications related to research it has helped
|
|
|
|
|
- send us feedback and suggestions for improvements
|
|
|
|
|
- send us bug reports when something goes wrong
|
|
|
|
|
- send us the modifications and improvements you have done to LiteDRAM.

We love open-source hardware and like sharing our designs with others.
|
|
|
|
|
|
|
|
|
|
LiteDRAM is developed and maintained by EnjoyDigital. Initial development
|
|
|
|
|
is based on MiSoC's LASMICON.
|
|
|
|
|
|
|
|
|
|
If you would like to know more about LiteDRAM or if you are already a happy
|
|
|
|
|
user and would like to extend it for your needs, EnjoyDigital can provide standard
|
|
|
|
|
commercial support as well as consulting services.
|
|
|
|
|
|
|
|
|
|
So feel free to contact us, we'd love to work with you! (and eventually shorten
|
|
|
|
|
the list of the possible improvements :)
