What is the addressable space for 32-bit memory address?
What is the addressable space for 32-bit memory address?
4 GB
The CPU register stores memory addresses, which is how the processor accesses data from RAM. One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 GB (4,294,967,296 bytes) of RAM.
How many byte addressable addresses can a 32-bit processor support?
4,294,967,296 bytes
For instance, a computer said to be “32-bit” also usually allows 32-bit memory addresses; a byte-addressable 32-bit computer can address 232 = 4,294,967,296 bytes of memory, or 4 gibibytes (GiB). This allows one memory address to be efficiently stored in one word.
What is the maximum directly addressable memory capacity of 32-bit microprocessor?
32-bit microprocessor with 32-bit instruction. First 8-bits consist of Opcode. Rest 24-bits consist operand address. Since 24 bits is used to address the operands the range of address lies between and , the maximum directly addressable memory capacity is which is equivalent to 16 Mega Bytes.
What will be extended memory size of a processor having 32-bit address lines?
Question: A microprocessor has a 32-bit address line. The size of the memory contents of each address is 8 bits. The memory space is defined as the collection of memory position the processor can address.
Why is memory byte addressable?
The 386SX, which addresses memory in 8-bit units but can fetch and store it 16 bits at a time, is termed byte-addressable. The advantage of word addressing is that more memory can be addressed in the same number of bits. The IBM 7094 has 15-bit addresses, so could address 32,768 words of 36 bits.
What is bit-addressable memory?
Bit-addressable objects are objects that may be addressed as words or as bits. Only data objects that occupy the bit-addressable area of the 8051 internal memory fall into this category. The Cx51 Compiler places variables declared with the bdata memory type into the bit-addressable area.
What is meant by addressable memory?
Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data.
How do you find the maximum directly addressable memory capacity?
If each chunk was a byte that would mean that the total addressable memory would be 16777216 bytes, or 16MB. Similarly, if each chunk was 4 bytes long, the total addressable memory would be (chunk size × number of addresses), or 4B×16M=64MB.
