The CPU of 8051 Architecture consists of eight-bit Arithmetic and Logic unit with associated registers like A, B, PSW, SP, the sixteen bit program counter and “Data pointer” (DPTR) registers.
The 8051’s ALU can perform arithmetic and logic functions on eight bit variables. The arithmetic unit can perform addition, subtraction, multiplication and division. The logic unit can perform logical operations such as AND, OR, and Exclusive-OR, as well as rotate, clear, and complement. The ALU also looks after the branching ‘decisions. An importa...
It is an 8-bit register. It holds a source operand and receives the result of the arithmetic instructions (addition, subtraction, multiplication, and division). The accumulator can be the source or destination for logical operations and a number of special data movement instructions, including look-up tables and external RAM expansion. Several func...
Many instructions implicitly or explicitly affect (or are affected by) several status flags, which are grouped together to form the Program Status Word. Fig. 12.3 shows the bit pattern of the program status word. It is an 8-bit word, containing the information as follows.
Stack Pointer :
The stack pointer register is 8 bit wide. It is incremented before data is stored during PUSH and ALL instructions. The stack array can reside anywhere in on-chip RAM. The stack pointer is initialized to 07H after a reset. This causes the stack to begin at location 08H.
Data Pointer (DPTR) :
The data pointer (DPTR) consists of a high byte (DPH) and a low byte (DPL). Its function is to hold a 16 bit address. It may be manipulated as a 16 bit data register or as two independent 8 bit registers. It serves as a base register in indirect jumps, lookup table instructions and external data transfer.
Fig: 12.4 shows the basic memory structure for 8051. It can access upto 64 K program memory and 64 K data memory. The 8051 has 4 Kbytes of internal program memory and 256 bytes of internal data memory. Each memory type has different addressing mechanism, different control signals, and a differennt function. Each may be added independently, and each...
Fig. 12.5 shows a map of Program Memory of 8051. In 8051, when the EA pin is connected to Vcc, program fetches to addresses 0000H through OFFFH are directed to the internal ROM and program fetches to addresses 1000H through FFFFH are directed to external ROM/EPROM. On the other hand when EA pin is grounded, all addresses (0000H to FFFFH) fetched by...
Fig. 12.9 shows a map of Data Memory Organisation of 8051 The 8051 can address upto 64 Kbytes of external data memory. The “MOVX” instruction is used to access the external data memory. The internal data memory space for Intel 8051 Architecture and 8031 Architecture is divided into three blocks : Lower 128 bytes, Upper 128 bytes and SFRs. The upper...
Unlike other microprocessors in the Intel family, 8051 uses memory mapped I/O through a set of special function registers that are implemented in the address space immediately above the 128 bytes of RAM. Fig. 12.12 shows special function bit addresses. All access to the four I/O ports, the CPU registers, interrupt-control registers, the timer/count...
It consists of 4 register banks and 144 general purpose bits forming boolean processor RAM. Fig. 12.12 shows RAM bit addresses. The register bank-select bits refer to four 8 byte regions at the bottom of memory. Certain instructions can access these registers in RAM directly with 1 byte instructions, since 3 bits of the instruction specify the desi...

Feb 20, 2023 · Intel 8031 and 80C31 are members of Intel MCS-51 family of 8-bit microcontrollers. 8031 / 80C31 have the same integrated peripherals as 8051 MCUs - 4 I/O ports, two 16-bit timers/counters, on-chip oscillator and a serial port. The MCUs have 128 bytes of internal RAM, and, in addition to that, can utilize up to 64 KB of external data memory.
