How many memory locations can be addressed by a microprocessor that uses 24 bit addressing? Answer:
Aroun 16 Kilo Bytes
of memory locations can be addressed.
How many memory locations can be addressed by a microprocessor that uses 28 bit addressing?
The DRAM chip has 16 rows and 12 columns, for a total of 28 address lines. 228 =
268,435,456 memory locations
. Also, 228 = 28 × 220 = 256 × 220 = 256 M.
How many memory location can be addressed by a microprocessor with 20 address line?
For example, an 8-bit-byte-addressable machine with a 20-bit address bus (e.g. Intel 8086) can address
2
20
(1,048,576)
memory locations, or one MiB of memory, while a 32-bit bus (e.g. Intel 80386) addresses 2
32
(4,294,967,296) locations, or a 4 GiB address space.
How many locations of memory can be addressed by the 8086 microprocessor?
For example, an 8-bit-byte-addressable machine with a 20-bit address bus (e.g. Intel 8086) can address
2
20
(1,048,576)
memory locations, or one MiB of memory, while a 32-bit bus (e.g. Intel 80386) addresses 2
32
(4,294,967,296) locations, or a 4 GiB address space.
How many memory locations can be addressed by a microprocessor with 16 address lines?
Using 16 bits, you can write
65536 addresses
(from 0 to 65535, that’s 65536 different addresses), and address 65536 bytes. 65536 bytes is 64kB. In computer science, b is bit, B is byte. The byte is the smallest amount of memory you can address.
How many unique addresses would be required to access 2 to the 16 memory cells?
How many unique addresses would be required to access 2 to the 16 memory cells? So 2 to the power of 16 is
65,536
, commonly referred to as 64K.
What is a 32-bit address?
A 32-bit address is
the address of a single byte
. Thirty-two wires of the bus contain an address (there are many more bus wires for timing and control). Sometimes people talk about addresses like 0x2000, which looks like a pattern of just 16 bits. But this is just an abbreviation for the full 32-bit address.
What is minimum and maximum mode in 8086 microprocessor?
The 8086 microprocessor can work in two modes of operations : Minimum mode and Maximum mode. In the minimum mode of operation the microprocessor do not associate with any co-processors and can not be used for multiprocessor systems. In the maximum mode the 8086
can work in multi-processor or co-processor configuration
.
How many registers does 8086 have?
The 8086 has
eight more or less general
16-bit registers (including the stack pointer but excluding the instruction pointer, flag register and segment registers). Four of them, AX, BX, CX, DX, can also be accessed as twice as many 8-bit registers (see figure) while the other four, SI, DI, BP, SP, are 16-bit only.
How many memory locations can be addressed?
Answer: It is
2^14 memory lacations
can be addressed by a microprocessor with 14 address lines.
What is the smallest and highest address?
Indeed, if the “smallest addressable unit” is a “4 byte word”, then it would follow that in 2^10 bytes there are 2^8 different addresses, which means that the
highest address is 2^8-1 or 255
.
How many locations of memory can you address with 12 bit memory address?
Each memory location is one byte, while the address is 12-bit, with the capability to address up to
4096 locations
.
How many addresses can a 16-bit address bus generate?
A 16-bit integer can store
2
16
(or 65,536)
distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.
How do memory addresses work?
A memory address is a unique identifier used
by a device or CPU for data tracking
. This binary address is defined by an ordered and finite sequence allowing the CPU to track the location of each memory byte. … Hardware devices and CPUs track stored data by accessing memory addresses via data buses.
How many address lines are required for 1MB memory?
“
20”
address lines or address bus are required to span “1MB” memory space.
How do I find my memory address range?
In your example for Range 1, you are correct. That is the size of the memory, stated in hexidecimal, in bytes. You may gain the most insight by first converting 00FF FFFF to a decimal number, then converting that number of bytes into megabytes. 1 MB = 1 Megabyte = 1024 * 1 KB = 1,048,576 bytes.
