# Caravel User Project: Rift2Chip 2330


## Attention

A Fake Code "LFSR16" and "Multiplier"is Uploaded.

### LFSR
A LFSR16 is instance, it will output four ramdom code in HEX to io. It will be connected to 7-segment seconds and display 4 numbers.
A IO can lock the LFSR, it will be connect to a switch.

### Multiplier
A Multiplier in Rift2Core is instance in 32-bits Mode. All ports are connected to la.
It's Boot4-WallceTree Multiplier.
--------------------------------------------


Based on Chisel3, Rift2Core is a 9-stage, dual-issue, out-of-order, 64-bits RISC-V Core, which supports RV64GC and M, S, U mode.

[RiftCore](https://github.com/whutddk/RiftCore) is the previous version of Rift2Core in Verilog.
