31 [> Description
32 --------------
33 First release of LiteX and the ecosystem of cores!
34
35 LiteX is a Migen/MiSoC based Core/SoC builder that provides the infrastructure to easily create
36 Cores/SoCs (with or without CPU).
37
38 The common components of a SoC are provided directly:
39 - Buses and Streams (Wishbone, AXI, Avalon-ST)
40 - Interconnect
41 - Common cores (RAM, ROM, Timer, UART, etc...)
42 - CPU wrappers/integration
43 - etc...
44 And SoC creation capabilities can be greatly extended with the ecosystem of LiteX cores (DRAM,
45 PCIe, Ethernet, SATA, etc...) that can be integrated/simulated/build easily with LiteX.
46
47 It also provides build backends for open-source and vendors toolchains.
