For each of the following properties, mark whether it is an advantage for a fixed or a variable-length instruction model for an ISA. (4 points) Write F in the cell that you believe is an advantage to a fixed-length ISA. Write V in the cell that you believe is an advantage to a variable-length ISA. [space] Saves space [fixed_pc_inc] PC can be incremented by a fixed value [simple_inst] Simplifies instruction decode [mult_addr] Makes it easy to support multiple memory addresses in a single instruction [hardware] Simplifies hardware implementation [code_read] Reduces the amount of code to be read from memory [size] The size of the instruction is known in advance [opcode_size] The opcode can control the size of the instruction

Given the following declaration of a struct, pack the members of the struct to minimize wasted space and respect alignment. Assume byte addressability and do not reorder members. Assume the ISA is Big Endian. struct x {  char a{3}; // values { 0x30, 0xAC, 0x20 }  short b;   // value 0xBEEF  int c;     // value 0x6121C0DE  char d;    // value 0xCA  short e;   // value 0xMEAL}; Not all the hex values are valid. Please copy the values into the table below (e. g. LE is not a valid hex but write 0xLE in the corresponding cell). Prefix all the hex numbers with 0x and use uppercase for alphabetical digits (e. g. for hex value 0xFF: xFF, FF, and ff will NOT be accepted). There will be point deductions for misformatted fields. Write uppercase N/A in any unused fields. Do not leave any leading or trailing whitespaces in each cell. Starting Address +0 +1 +2 +3 0x1024 [x1024] [x1025] [x1026] [x1027] 0x1028 [x1028] [x1029] [x102A] [x102B] 0x102C [x102C] [x102D] [x102E] [x102F] 0x1030 [x1030] [x1031] [x1032] [x1033]
