Florent Kermarrec 67a09aef05 soc/interconnect/stream: add Monitor module 
Generic module to monitor endpoints activity: tokens/overflows/underflows that
can be plugged on a endpoint. Can be useful for various purpose:
- endpoint bandwidth calculation.
- underflows/overflows detection.
- etc...

Merge pull request #254 from mithro/crc-smaller 
Add @xobs' smaller CRC version
 2019-09-03 07:23:32 +02:00
Tim 'mithro' Ansell 2a41f0d2a4 Use `SMALL_CRC` to enable smaller CRC versions. 
@xobs created a smaller code size version of the CRC functions. Enable
these if someone uses the `SMALL_CRC` define.

software: use native toolchain for same host, target architectures
 2019-08-23 21:36:51 +02:00
Gabriel L. Somlo 6d844a038a software: use native toolchain for same host, target architectures 
LiteX rightfully assumes that most often the target software must
be cross-compiled from an x86 host platform. However, LiteX can be
also built on a 'linux-riscv64' platform (e.g. Fedora's riscv64
port), where the software for riscv64 targets should be compiled
using the native toolchain.

update with hyperram and other changes
 2019-08-16 14:36:59 +02:00
Florent Kermarrec 4990bf33c0 soc/core: simplify/cleanup HyperRAM core 
- rename core to hyperbus.
- change layout (cs_n with variable length instead of cs0_n, cs1_n).
- use DifferentialOutput when differential clock is used.
- add test (python3 -m unittest test.test_hyperbus).

Usage example:
from litex.soc.cores.hyperbus import HyperRAM
self.submodules.hyperram = HyperRAM(platform.request("hyperram"))
self.add_wb_slave(mem_decoder(self.mem_map["hyperram"]), self.hyperram.bus)
self.add_memory_region("hyperram", self.mem_map["hyperram"], 8*1024*1024)
