One of the main advantages of software architecture is that it provides high productivity to the software team. Having a clear design of a complete system as a starting point provides a solid basis for developers to follow.Įach developer will know what needs to be implemented and how things relate to meet the desired needs efficiently. It is essential to have proper software architecture, mainly for a large software system. The architect plans the structure of the system to meet the needs like these. To form an architecture, the software architect will take several factors into consideration: In short, it is a big picture or overall structure of the whole system, how everything works together. It defines the elements included in the system, the functions each element has, and how each element relates to one another. Software architecture provides a basic design of a complete software system. The software team is tied to many practical concerns, such as: It is needed to think big from multiple perspectives with quality and design in mind. The read signal is used to read data from memory or other devices, the write signal is used to write data to memory or other devices, the interrupt signal is used to signal the microprocessor that an interrupt has occurred, and the reset signal is used to reset the microprocessor to its initial state.Ĩ085 is an 8-bit, general-purpose microprocessor.Software architecture is all about how a software system is built at its highest level. The control bus includes signals such as the read signal, write signal, interrupt signal, and reset signal. The control bus is a set of signals that controls the operations of the microprocessor, including the read and write operations. The address bus is used to select the memory location or device that the microprocessor wants to access. The address bus is a 16-bit bus that is used to address memory and other devices. The data bus is bidirectional, which means that it can be used to read data from memory or write data to memory. The data bus is an 8-bit bus that is used to transfer data between the microprocessor and memory or other devices. The carry flag is set when an arithmetic operation generates a carry, the zero flag is set when the result of an arithmetic or logical operation is zero, the sign flag is set when the result of an arithmetic or logical operation is negative, and the parity flag is set when the result of an arithmetic or logical operation has an even number of 1 bits. These flags include the carry flag, zero flag, sign flag, and parity flag. The flags register is an 8-bit register that contains status flags that indicate the result of an arithmetic or logical operation. The instruction register is used by the microprocessor to decode and execute instructions. The instruction register is an 8-bit register that contains the current instruction being executed.
