[> Description
|
||
--------------
|
||
First release of LiteX and the ecosystem of cores!
|
||
|
||
LiteX is a Migen/MiSoC based Core/SoC builder that provides the infrastructure to easily create
|
||
Cores/SoCs (with or without CPU).
|
||
|
||
The common components of a SoC are provided directly:
|
||
- Buses and Streams (Wishbone, AXI, Avalon-ST)
|
||
- Interconnect
|
||
- Common cores (RAM, ROM, Timer, UART, etc...)
|
||
- CPU wrappers/integration
|
||
- etc...
|
||
And SoC creation capabilities can be greatly extended with the ecosystem of LiteX cores (DRAM,
|
||
PCIe, Ethernet, SATA, etc...) that can be integrated/simulated/build easily with LiteX.
|
||
|
||
It also provides build backends for open-source and vendors toolchains.
