Sarah L. Harris David Harris in Digital Design and Computer Architecture 2022 6.7 Evolution of the RISC V Architecture. RISC V was designed to be a commercially viable open source computer architecture that is robust efficient and flexible. RISC V differentiates itself from other architectures because it is open source uses base instruction sets to ease compatibility
A RISC V core might have additional specialized instruction set extensions or an added coprocessor. We use the term coprocessor to refer to a unit that is attached to a RISC V core and is mostly sequenced by a RISC V instruction stream

RISC V pronounced risk five is an open standard instruction set architecture ISA based on established reduced instruction set computer RISC principles. V is the fifth generation RISC reduced instruction set computer which means that it has been four RISC processor prototype chip. Unlike most other ISA designs the RISC V ISA is provided under open source
The RISC V OTTER Vector Extension Instruction Set The RISC V OTTER Vector Extension RVV is an addition to the RV32I instructions for the open source RISC V architecture. This instruction set is based on a subset of the instructions presented in the version 0.7.1 draft of the RISC V ‘V’ Vector Extension
RISC V is much simpler ISA than x86 so it should be much easier to programming with RISC V For programming embedded system with RISC V Youtube has video series for hand on instructions of Programming a microcontroller with RISC V 5. Refer to the following book and GNU assembler manual to write a full featured assembly program.
Introduction. This document describes the 6 stage single issue Ariane CPU which implements the 64 bit RISC V instruction set. It fully implements I M and C extensions as specified in Volume I User Level ISA V 2.1 as well as the draft privilege extension 1.10. It implements three privilege levels M S U to fully support a Unix like operating

Nov 30 2019 NOP is a pseudoinstruction that expands to ADDI x0 x0 0.The x0 or zero is a read only register dedicated to the value zero i.e. it is hardwired to zero for every single bit. Whatever is written to this register is simply discarded since its value can t be modified. From The RISC V Instruction Set Manual Volume I Unprivileged ISA . The NOP instruction does not
12.2. Interrupt Entry and Exit¶. When a RISC V hart takes an interrupt the following occurs The value of mstatus.MIE is copied into mstatus.MPIE and then mstatus.MIE is cleared effectively disabling interrupts.. The current PC is copied into the mepc register and then PC is set to the value of mtvec.In the case where vectored interrupts are enabled PC is set to mtvec.BASE
