Therefore, the permissible memory location offered by the microprocessor is 1 MB. More simply we can say that it can store 1 megabyte of data inside it. Along with the operation performed by the ALU of the microprocessor, the arithmetic and logic unit of microprocessor can also perform multiplication and division operation. And the EU executes the perfected instructions present in the instruction queue. The presence of an instruction queue in acts as an advantageous factor when compared with the microprocessor.

This is so because, by the help of instruction queue, BIU can prefetch the instructions and can store them in 6-byte instruction pre-fetch queue. This somehow reduces the instruction execution time and resultantly the overall efficiency of the system. Thus has two operating modes: minimum mode and maximum mode. In case of a single processor system, it operates in minimum mode.

While for multiple processors, operates in maximum mode. Due to advanced architecture and more providable features, is more expensive than the microprocessor. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.
