WebDec 4, 2024 · The Intel 8086 accessed memory using 20-bit addresses. But, as the processor itself was 16-bit, Intel invented an addressing scheme that provided a way of mapping a 20-bit addressing space into 16-bit words. WebDec 27, 2024 · The 8086 microprocessor has 8 registers each of 8 bits, AH, AL, BH, BL, CH, CL, DH, DL as shown below. Each register can store 8 bits. To store more than 8 bits, we have to use two registers in pairs. There are 4 register pairs AX, BX, CX, DX. Each register pair can store a maximum of 16-bit data.
The 8086 (also called iAPX 86) is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released.
