Fig. 10From: A buffer overflow detection and defense method based on RISC-V instruction set extensionAn implement method of nxcheck instruction in RISC-V security hardware. Left part describes the instruction decoding process. opcode, funct3 and funct7 fields are combined to set the enable signal(en). When enabled, read the nxval as result from the store place corresponding to addr-reg. If error occurs, nxval will be the error codeBack to article page
