8-bit CPUs use an 8-bit data bus and can therefore
access 8 bits of data in a single machine instruction
. The address bus is typically a double octet (16 bits) wide, due to practical and economical considerations. This implies a direct address space of 64 KB (65,536 bytes) on most 8-bit processors.
Why is it called 8-bit?
In computer science, the term word refers to the standard computational unit of a machine. That means an 8-bit processor has a word that’s eight bits long, which in turn means that
the C.P.U. processes eight bits in one operation
.
What do 8 bits represent?
Hexadecimal, Octal, Bits, Bytes and Words.
The most common grouping is 8 bits, which forms
a byte
. A single byte can represent 256 (2
8
) numbers. Memory capacity is usually referred to in bytes.
Which of the following has 8-bit data bus?
8085
microprocessor assembly language consists of 246 instructions. An 8-bit microprocessor signifies that it has 8-bit data bus. 8085, Z-80 and 6502 are 8-bit microprocessors whereas 68000 is a 16-bit microprocessor.
What is better 8-bit or 16 bit?
In terms of color, an 8-bit image can hold 16,000,000 colors, whereas a
16-bit
image can hold 28,000,000,000. Note that you can’t just open an 8-bit image in Photoshop and convert it to 16-bit. … This extra bit depth does come at a cost. More bits means bigger file sizes, making images more costly to process and store.
What is the largest number that can be held in 8 bits?
With 8 bits, the maximum number of values is
256
or 0 through 255.
Is 8-bit a good brawler?
8-BIT is a Common Brawler who is unlocked as a Trophy Road reward upon reaching 6000 Trophies. He has
high health
and a high damage output, but suffers by having the slowest movement speed of any Brawler.
Is Minecraft an 8-bit game?
Therefore,
Minecraft is indeed an “8-bit” game
. Just like every game ever made with Flixel, and a large number of other flash games.
Is binary always 8-bit?
| Decimal, Base 10 Hexadecimal, Base 16 | 8 8 | 9 9 | 10 A | 11 B |
|---|
Which one is not a 8-bit microprocessor?
INTEL8085,
MOTOROLA6800
, ZILOG280 are 8-bit microprocessors while FAIRCHILD9440 is a 16 bit microprocessor.
Which is not a 8-bit microprocessor?
1. Which of the following microprocessors is not 8 bit microprocessor? Ans d)
68000
, The Motorola 68000 (“’sixty-eight-thousand’”; also called the m68k or Motorola 68k, “sixty-eight-kay”) is a 16/32-bitCISC microprocessor core designed and marketed by Motorola Semiconductor Products Sector.
Should I use 8 or 16-bit Photoshop?
1 Correct answer.
Use 8-bit
. You could start out in 16-bit if you are doing heavy editing to photographic images, and convert to 8-bit when you’re done. 8-bit files have 256 levels (shades of color) per channel, whereas 16-bit has 65,536 levels, which gives you editing headroom.
Is 16bit Better than 32bit?
While a 16-bit processor can simulate 32-bit arithmetic using double-precision operands,
32-bit processors are much more efficient
. While 16-bit processors can use segment registers to access more than 64K elements of memory, this technique becomes awkward and slow if it must be used frequently.
How do I know if my image is 8-bit or 16-bit?
- Open you image in Photoshop.
- Go to the top menu and click image > mode.
- Here you will see a check mark next to the Bits/Channel your image is set to.
How do you express 13 in binary?
13 in binary number system is
1101
and 94 is 1011110.
