Intel 80486

The Intel 80486, also known as the i486 or 486, is a microprocessor that was produced by Intel from 1989 to 1993. It was the successor to the Intel 80386 and was the first microprocessor to use the 32-bit x86 instruction set.

The 80486 was introduced in 1989 and was the first Intel chip to use more than 1 million transistors. It had a clock speed of up to 33 MHz and a 32-bit data bus. It was also the first Intel chip to support a math coprocessor and the first to be used in a PC.

The 80486 was succeeded by the Intel Pentium in 1993. Does 80486 have cache memory? Yes, the 80486 has cache memory. It is located on the chip itself, and is used to store frequently accessed data. When did the Intel 486 come out? The Intel 486 was released in April 1989. How much is size of the 80486 CPU bit? The 80486 CPU bit is 32 bits.

What is the basic features of 80486?

The 80486 is a microprocessor introduced in 1989. It is a complete superset of the 8086 and 80186 microprocessors, and adds several enhancements, most notably the inclusion of a floating-point unit (FPU). The initial clock speed of the 80486 was 16 MHz, but later versions ran at speeds up to 100 MHz.

The 80486 has a 32-bit internal data bus and a 24-bit address bus, giving it a theoretical maximum memory address space of 16 MB. It also has on-chip cache memory, which can be configured as either 8 KB of data cache or 8 KB of instruction cache, or a split of 4 KB of data cache and 4 KB of instruction cache.

The 80486 is capable of executing up to two instructions per clock cycle, thanks to its use of pipelining. It also has register renaming, which allows it to avoid many of the data hazards that can slow down other microprocessors. What are the functional units of 80486? The functional units of the 80486 are the arithmetic logic unit (ALU), the control unit, the instruction decoder, the registers, and the cache.
