Answer #1

Fixed-width instructions make it difficult to decode because the number of bytes each instruction is using can change. this statement is False.

A register is incremented by either a byte or a word to advance to the next element in an array with Indexed Addressing. this statement is True.

The "la" instruction is an example of a pseudo-instruction. this statement is True.

PC-relative addressing uses the program counter as the base address. this statement is True.

PC-relative addressing uses the Immediate Type of instruction format because one of the arguments contains the number of bytes to be skipped over. this statement is True.

The offset is a register value that represents how many bits from the beginning address the value resides. this statement is True

The index value of the array is placed in a register in Indexed Addressing.so option (B) is correct

The base address of an array is placed in the register in Base Addressing Mode.so option (A) is correct.

A register points to the beginning address of an array. option (A) is correct.

A register is initialized with zero to advance through an array. option (B) is correct.

The last operand in this instruction format is a constant in Immediate type. so option (B) is correct.

12. This instruction format stores an address in 26 bits. option (C) is correct

13. This instruction format has one field that is limited to 16 bits in size. option (A) is correct.

14. This instruction format uses direct addressing to access data. option (A) is correct.

15. The add, sub, and jr are instructions that use this type of instruction formating. option (C) is correct.

16. The mult and div instructions use this type of instruction format. option (A) is correct.

17. The beq uses this type of instruction format. option (C) is correct.

18. The load and store commands use this type of instruction format. option (A) is correct.
