Question

Select all of the following statements that are true. If you don't recall the answers from the lecture, you are welcome to search the course Module slides or use your favorite Internet search engine. 8-bit Central Processing Units (CPUs) generally have registers that each store 8 bits. 16-bit CPUs have registers that each store 16-bits. 32-bit CPUs have registers that each store 32-bits. 64-bit CPUs have registers that each store 64-bits. Since most machine instructions perform operations on the bits within one or more registers having 64-bits in each register means at least some instructions can perform operations on 64 bits all at once. For the same CPU generally has instructions that operate on 32 bits at a time. reason, a 32-bit Addresses are not used to access non-volatile memory If a Central Processing Unit (CPU) is byte-addressable, it means that it is able to read any bytes in memory one by one. In other words, operation. a machine instruction can read or use one byte without necessarily using any other bytes during the same Registers are often used to store addresses. The number of unique addresses determines the number of Machine Addressable Units (MAUs) that may be read or written. A 32-bit CPU may therefore be limited to reading or writing 4,294,967,296 unique MAUs

Explanation / Answer

Answer 1: True

Reason: CPU artitecture depends on register bits, address bit bits, therefore 32bit cpu have 32 bit register, address bus, data bus.

Answer 2: False

Reason: Addresses are used to access any memory whether they are volatile or non-volatile, only registers have single address, so there is no need of address.

Answer 3: True

Reason: Yes! byte addressable CPU is designed for read any byte in memory one by one.

Answer 4: True

Reason: A 32-bit computer can address 232 = 4,294,967,296 bytes of memory, or 4 gibibytes

Answer 5: True

Reason: Any type of CPU(basically two types) have CU, ALU and memory, apart from this von Neumann architecture does not allow execution from external storage. Example: Calculator, Gaming Console etc.

Answer 6: False

Reason: ALU only performs arithmetic operation like adding, substracting, shifting, comparing etc., CU is used for decode instructions.

Answer 7: True

Reason: Machine instructions are also encoded in bits as a binary instruction code.
