MCS-51 - Wikipedia
The Intel MCS-51 (commonly termed 8051) is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton. Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary … Afficher plus
The 8051 architecture provides many functions (central processing unit (CPU), random-access memory (RAM), read-only memory Afficher plus
Intel's first MCS-51 microcontroller was the 8051, with 4 KB ROM and 128 byte RAM. Variants starting with 87 have a user programmable EPROM, sometimes UV erasable. Variants with a C as the third character are some kind of CMOS. 8031 and 8032 are … Afficher plus
The microarchitecture of the Intel MCS8051 is proprietary, but published features suggest how it works. It is a multi-cycle processor. … Afficher plus
Instructions are all 1 to 3 bytes long, consisting of an initial opcode byte, followed by up to 2 bytes of operands.
1⁄4 of the opcode bytes, x0–x3, are used for irregular opcodes. Afficher plusThe MCS-51 has four distinct types of memory: internal RAM, special function registers, program memory, and external data memory. To access these efficiently, some compilers … Afficher plus
The only register on an 8051 that is not memory-mapped is the 16-bit program counter (PC). This specifies the address of the next instruction to execute. Relative branch instructions supply an 8-bit signed offset which is added to the PC.
Eight general … Afficher plusThere are various high-level programming language compilers for the 8051. Several C compilers are available for the 8051, most of which allow the programmer to specify where each … Afficher plus
