1. Fill in the blank spaces The SIC machine has memory architecture consisting of 8-bit bytes, and 3 bytes form consecutive a word. Instructions on a SIC machine are 24 bits in length; there are 4 bits in the opcode field and 6 bits in the address field of the instruction; there are total 32768 bytes in the memory.

Question
1. Fill in the blank spaces The SIC machine has memory architecture coônsisting of 8-bit bytes, and 3 bytes form a word. Instructions on a SiC machine are 24 consecutive bits in length; there are 4 bits in the opcode field and 6 bits in the address field of the instruction; there are total 32768 bytes in the memory. There are five registers (A, X, L, PC, and SW) defined in the standard SIC machine, each register has bits in length. Among these registers, is used for index addressing, contains the address of the next instruction, is typically used for arithmetic operations, and contains a variety of information such as condition code, and stores the return address for subroutine jump. The maximum memory available on a SIC/XE machine is MB (megabyte), since the SIC/XE has up to bits in the address field of the instruction. Most assemblers make two passes over source program. Pass performs most of the actual translation. Pass scans the source for label definitions and assigns address. W II F8 F5 F6 F7 F9 & 6.
