Consider a CPU with an 18-bit data bus and a 26-bit address bus e) How wide (in bits) is the Data Address Register? f) How wide (in bits) is the Data-In Register? g) How wide (in bits) is the Data-Out Register?

Consider a CPU with an 18-bit data bus and a 26-bit address bus e) How wide (in bits) is the Data Address Register? f) How wide (in bits) is the Data-In Register? g) How wide (in bits) is the Data-Out Register?Explanation / Answer
Ans: The data bus carries data to be written to memory or data to read from memory.
The address bus is used specifies the address where to store in memory.
Here address bus is 26 bit and the data bus is 18 bit.
e) How wide (in bits) is the Data Address Register?
Ans: As the address bus is 26 bit. So data address register needs 26 bits to access the memory location.
f) How wide (in bits) is the Data-In Register?
Ans: As the data bus is 18 bit. so Data-In Register needs 18 bits to hold data for memory.
g) How wide (in bits) is the Data-Out Register?
Ans: As the data bus is 18 bit. so Data-Out Register needs 18 bits to hold data from memory
