ADD Instruction in Intel 8051 (MCS-51) Microcontroller
The ADD instruction tells the microcontroller’s CPU to add the source byte to register A and put the result in register A. Recall, A is the accumulator register typically used for all arithmetic and logic instructions. The ADD instruction is usually in the following form: ADD A, source ; ADD the source operand to the…

SIMD, MISD & MIMD Multiple Processor Architectures
Introduction Parallel processing, in which applications are partitioned into multiple tasks that are executed concurrently by multiple processors is used for high-throughput needs where even the single fastest computer cannot be good enough. Multiple processor system architectures differ widely in the number of processors used, the techniques in which applications are partitioned and mapped onto…
