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. General-purpose registers are used … WebMDR is the register of a computer ’s control unit that contains the data to be stored in the computer storage (e.g. RAM), or the data after a fetch from the computer storage. It acts like a buffer and holds anything that is copied from the memory ready for the processor to use it. MDR hold the information before it goes to the decoder.
Web16-bit architecture. The MIT Whirlwind (c. 1951) was quite possibly the first-ever 16-bit computer. It was an unusual word size for the era; most systems used six-bit character code and used a word length of some multiple of 6-bits. This changed with the effort to introduce ASCII, which used a 7-bit code and naturally led to the use of an 8-bit multiple which … WebFour 32-bit data registers are used for arithmetic, logical, and other operations. These 32-bit registers can be used in three ways −. As complete 32-bit data registers: EAX, EBX, ECX, EDX. Lower halves of the 32-bit registers can be used as four 16-bit data registers: AX, BX, CX and DX. Lower and higher halves of the above-mentioned four 16 ...
