- you wrote a software simulation of a computer that executes programs written in Simpletron Machine Language (SML). In this exercise, we propose several modifications and enhancements to the Simpletron Simulator. In Exercises 19.30–19.34, we propose building a compiler that converts programs written in a high-level programming language (a variation of BASIC) to SML. Some of the following modifications and enhancements may be required to execute the programs produced by the compiler. [Note: Some modifications may conflict with others and therefore must be done separately.] Modify the simulator to handle string input. [Hint: Each Simpletron word can be divided into two groups, each holding a two-digit integer. Each two-digit integer represents the ASCII decimal equivalent of a character. Add a machine-language instruction that inputs a string and store the string beginning at a specific Simpletron memory location. The first half of the…Interrupts are system wide events that stop the execution of a currently running process. Examples of interrupts include (but are not limited to) mouse clicks, process termination, key presses, etc. Some interrupts are considered as more important to be handled first then the others. For example, a hardware interrupt such as hard drive read operation has lesser priority than a memory read. In this way, the most appropriate data structure for representing of such events is the priority queue. Demonstrate by writing an algorithm or a flowchart how to insert the following interrupts in a heap so the highest priority element should move out first.

- Assume a primitive time-sharing operating system is running on a computer with 50,000 32-bit words of main memory, with the resident monitor consuming 10,000 of that. When control is to be assigned to an interactive user, the user’s program and data were loaded into the remaining 40,000 words of main memory. A program is always loaded to start at the location of the 10,000th word; this simplified both the monitor and memory management.

(b) The monitor decides to load Job2 and transfer control to it. (c) Next, the monitor decides to load Job3 and transfer control to it.

- Abstraction is a concept in computer organization and architecture that is clearly demonstrated by the implementation of instruction set architecture. It copes with complexity and hide unneeded details. Briefly discuss two aspects of abstraction.Please written by computer source Two main techniques are used for memory management in modern computers and operating systems, as described in this module's readings: paging and segmentation. Sometimes they are combined in a segmentation with paging scheme. Design a memory management scheme for a 50 bit computer architecture, using paging, segmentation or both, as described in this module's readings. Your post should include a clear translation scheme from a 50 bit logical address to a 50 bit physical address including a picture that shows how this translation takes place. In particular, each field of the logical address must be clearly depicted and its length in bits must be specified. The proposed scheme must be at least somewhat realistic; for this reason, simple paging and simple segmentation schemes are automatically disqualified, due to the impossible requirements imposed on the implementation in this case (50 bits addresses).Abstraction is a key concept in computer organization and design, and one example of its use is seen in the implementation of instruction set architecture. It is able to process a large amount of data while simultaneously hiding data that isn't required for operation. Explain two characteristics of abstraction, then provide a definition of abstraction.
