What is the difference between bit addressable and byte addressable?
In Byte addressable we can only access the data by byte by byte i.e whole bunch of 8 bits. but in bit addressable addresses we can access or manipulate each bit individually.
What is bit address and byte address?
They are not really using the terms right, byte addressable is what we are used to an address represents a unique byte in memory or the memory space. Bit addressable would mean that each bit in the memory space has a unique address, which is not the case.
What is a bit what is a byte What is the difference between a byte and a word of memory?
A byte is 8 bits and a word is the smallest unit that can be addressed on memory.
What is bit addressable area?
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 are bit addressable memory locations?
The bit-addressable RAM locations are 20H to 2FH. These 16 bytes provide 128 bits of RAM bit-addressability since 16×8= 128. They are addressed as 0 to 127 (in decimal) or 00 to 7FH.
Is a gigabit the same as a Gigabyte?
A gigabit is 109 or 1,000,000,000 bits. It is one-eighth the size of a gigabyte (GB), which means a gigabit is eight times smaller than a gigabyte. Additionally, Gigabits are mostly used to measure data transfer rates of local networks (Ethernet) and Input/Output (I/O) connections.
What is the byte address of memory word?
When the data space in the cell = 8 bits then the corresponding address space is called as Byte Address. When the data space in the cell = word length of CPU then the corresponding address space is called as Word Address.
What is a 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.
Why do computers use bytes for address representation?
When computers were so costly that they were only or mainly used for science and engineering, word addressing was the obvious mode. As it became cost-effective to use computers for handling text, hardware designers moved to byte addressing.
Which of the following address is bit addressable?
Which of the following is bit-addressable register? Explanation: The registers, accumulator, PSW, B, P0, P1, P2, P3, IP, IE, TCON and SCON are all bit-addressable registers. Explanation: The registers, DPH and DPL are the higher and lower bytes of a 16-bit register DPTR.
