A computer has the flowing instruction and integer format. The instruction consists of 4 bits opcode, 1 bit (M) that indicales the mode and the remaining bits are used either for immediate (when M=O) or memory address (when M=1) las shown below). Each memory location contains 16 bits. Opfer Operand tom/em (11 ) Instruction Form Based on this answer the following questions: (All answers must be in decimal, ie. for 2/3 enter 8. and so on) Assume that the immediate operand contains an unsigned number, what is the largest immediate operande What is the largest memory size in KBytes) that can be accessed directly_KB How many opcodes can be used for operations in this machine
