Which of the processor’s stack does not contain the top-down data structure?Ĭlarification: The 8051 stack is not a top-down data structure, like other Intel processors.Ĭlarification: The architecture of 8051 consists of 4 latches and driver pairs are allotted to each of the four on-chip I/O ports. The registers that contain the status information isĬlarification: The set of flags of program status word contains the status information and is considered as one of the special function registers.Ĥ. In other instructions, it may just be used as a scratch pad.ģ. The register that can be used as a scratch pad isĬlarification: B register is used to store one of the operands for multiply and divide instructions. The register that may be used as an operand register isĬlarification: In some instructions, the Accumulator and B register are used to store the operands.Ģ. they’re popularly used for educational purposes to realize experience as they’re available at low cost.Microprocessor Multiple Choice Questions on “Architecture of 8051”.ġ. Single-Board MC also called Development Board Microcontroller built onto one computer circuit Board (PCB). These features of Microcontrollers make it a perfect choice for embedded applications. MC’s works at lower speeds, and needs less power. they’re available with on board Memory and I/O Ports which eliminates building a circuit that has separate external RAM, ROM and Peripheral chips. they’re dedicated to execute specific task that’s programmed and stored in ROM. Microcontrollers also are called as “special purpose computers”. it’s also called MC or MCU (Microcontroller Unit) which may be a compact digital processor on Metal-Oxide-Semiconductor Chip. Microcontroller may be a device that captures input, processes it and generates output supported knowledge captured.

Being programmable is what makes microcontroller unique. Microcontroller is an microcircuit (IC) which will be programmed to perform a group of functions to regulate a set of electronic devices.
