In this lab, you will perform two tasks, one as an assembler and the other as disassembler. An assembler is a computer program that translates assembly language to machine language, by encoding assembly instructions with their binary representation. A disassembler is a computer program that translates binary machine language into assembly languagethe inverse operation to that of an assembler. The two tasks are:

1) given RISC-V assembly instructions, identify the class and encoding format of the instructions and encode them into 32-bit instruction words, and

2) given instruction words in hexadecimal format, decode the instructions and write down their assembly instructions. Encoding format and decoding of RISC-V instructions are studied in book chapter 2.4 (2s complement binary representation), 2.5 (R-, I- and Sformat instruction encoding for arithmetic, logic, load and store instructions) and 2.10 (SB- and J-Format encoding for branch and jump instructions, and decoding instructions). You should review the related lecture slides or the text book sections before working on the lab.
