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 is the previous version of Rift2Core in Verilog.
