   This is the reason why we have 80386SX version of the 80386 microprocessor. Generally, we consider 80386 as 80386DX, a processor with 32-bit of data bus. 80386 Microprocessor is a 32-bit processor that holds the ability to carry out 32-bit operation in one cycle. It has data and address bus of 32-bit each.

   What is the difference between 80386DX and 80387SX?

   • The 80386DX addresses 4G bytes of memory through its 32-bit data bus and 32-bit address. The 80386SX, more like the 80286, addresses 16M bytes of memory with its 24-bit address bus via its 16-bit data bus. The 80386SX was developed after the 80386DX for applications that didn’t require the full 32-bit bus version.

   Mar 9, 2023 · For accessing memory and registers, the 80386 microprocessor provides several addressing modes. These addressing modes govern how a processor interprets a memory address or register supplied in an instruction. The 80386DX provides a total of 11 addressing modes for instructions to specify operands.
