Question

39. If a system's instruction set consists of an 8-bit opcode, what is the maximum number of output signal lines required for the control unit?

A) 8 B) 64 C) 128 D) 256

40. If a system's entire set of microoperations consists of 41 statements, how many bits must be used for its microop code?

A) 4 B) 5 C) 6 D) 41

41. If a system's entire set of microoperations consists of 92 statements, how many bits must be used for its microop code?

A) 7 B) 8 C) 64 D) 92

42. In order to pass parameters to subprograms a(n) ____________ must be implemented to support the ISA.

A) bus B) assembler C) counter D) stack

43. _______ memory allows data to be both read from and written to easily and rapidly.

A) EPROM B) ROM C) RAM D) PROM

39) D

40) C

since it contain 41 operationswe need 6 bits to represents opcodes from 0-40 (000000 to 101000)

41) A

since it contain 92 operations we need 7 bits to represents opcodes from 0-91 (0000000 to 1011101)

42) D

stack

43) C

all ROMs are read only
