I was looking into Linux support for the RISC-V 32 Bit and came across the following compile instructions:
make ARCH=riscv CROSS_COMPILE=riscv32-unknown-linux-gnu- -j $(nproc)
The issue is that ri...

Understanding the difference between overflow and carry flags
I am designing a 16 bit ALU in verilog based on an existing RISC ISA. The ISA says that the carry flag is set when the operation is unsigned, and overflow is set when the operation is signed. The
