How many memory locations can be addressed by a microprocessor with 20 address lines?
For example, an 8-bit-byte-addressable machine with a 20-bit address bus (e.g. Intel 8086) can address 220 (1,048,576) memory locations, or one MiB of memory, while a 32-bit bus (e.g. Intel 80386) addresses 232 (4,294,967,296) locations, or a 4 GiB address space.
What is the maximum memory addressable using 28 address lines?
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 locations can be addressed by 14 address lines?
It is 2^14 memory lacations can be addressed by a microprocessor with 14 address lines. Answer: 2 ^ 14 memory location can be addressed by 14 bit address line.
What is the maximum number of memory locations that can be addressed by a chip with 16 address pins?
65,536 bytes
How many memory locations can be accessed by processor if it has 16 address lines?
If an address bus for a given computer has 16 lines, what is the maximum amount of memory it can access? – Quora. The number of memory words addressed on a bus is 2 to the power of the width of the address bus, in this case 16. So 2 to the power of 16 is 65,536, commonly referred to as 64K.
Is Little Endian in C?
Since size of character is 1 byte when the character pointer is de-referenced it will contain only first byte of integer. If machine is little endian then *c will be 1 (because last byte is stored first) and if machine is big endian then *c will be 0.
What is big endian and little Indian?
Big-endian is an order in which the “big end” (most significant value in the sequence) is stored first (at the lowest storage address). Little-endian is an order in which the “little end” (least significant value in the sequence) is stored first.
Is Intel big endian or little endian?
Different microprocessor vendors use different byte-ordering schemes. For example, Intel processors have traditionally been little-endian. Motorola processors have always been big-endian. Big-endian is an order in which the “big end” (the most-significant byte) is stored first.
Is AMD Little Endian?
To my knowledge, all of AMD’s processors have been x86-compatible, with some extensions like x86_64, and thus are necessarily little-endian.
What is the advantage of little endian?
The advantages of Little Endian are: It’s easy to read the value in a variety of type sizes. For example, the variable A = 0x13 in 64-bit value in memory at the address B will be 1300 0000 0000 0000 . A will always be read as 19 regardless of using 8, 16, 32, 64-bit reads.
Is Mac big endian or little endian?
In general, Intel architectures are little-endian, while most, but not all, Unix/RISC machines are big-endian….Architectural Issues.
| CPU type | Operating system | Endian-ness |
|---|---|---|
| Intel x86 | Windows | little-endian |
| Intel x86 | Linux | little-endian |
| Intel x86 | Solaris x86 | little-endian |
| Motorola PowerPC | Mac OS X | big-endian |
How do I know if my machine is little endian?
NET: Check the value of BitConverter. IsLittleEndian . If the output starts with a 1 (least-significant byte), it’s a little-endian system. If the output starts with a higher digit (most-significant byte), it’s a big-endian system.
What is little endian format?
Specifically, little-endian is when the least significant bytes are stored before the more significant bytes, and big-endian is when the most significant bytes are stored before the less significant bytes. When we write a number (in hex), i.e. 0x12345678 , we write it with the most significant byte first (the 12 part).
