Computer memory management system

Kirk, III, Whitson John (Greenwood, MO) · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023

A computer memory management system utilizing a memory structure system of "intelligent" pointers in which information related to the use status of the memory structure is designed into the pointer. Through this pointer system, The present invention provides essentially automatic memory management (often referred to as garbage collection) by allowing relationships between objects to have definite memory management behavior by use of coding protocol which describes when relationships should be maintained and when the relationships should be broken. In one aspect, the present invention system allows automatic breaking of strong links to facilitate object garbage collection, coupled with relationship adjectives which define deletion of associated objects. In another aspect, The present invention includes simple-to-use infinite undo/redo functionality in that it has the capability, through a simple function call, to undo all of the changes made to a data model since the previous `valid state` was noted.

Simulating Computer Memory Circuit

Wenxuan Wang · 2022

As the computer plays a more and more significant role in people's life, scientists have been trying to improve its capacity to bring more convenience to computer users. One way to achieve the purpose would be to enhance the capability of computer memory, which mainly reads and stores information stored in bits. The overall goal of the paper is to find directions to improve the capacity of computer memory that utilizes the RC circuit to work. It firstly lays out potential circuit designs that could ensure the functionality of computer memory. Then, a controlled experiment is conducted to investigate the relationship between different parameters of the circuit and dependent variables that are associated with the capability of the capacitor. Following that, the paper justifies the observations of the experiment with formulas related to electric circuit. Finally, it outlines the logical conclusions that follow from the experiment, the most important of which is that decreasing the conductance value of resistors and increasing the capacitance value of the capacitor would reduce energy consumption of the circuit, which would be applied to the improvement of resistive computer memory.

Performance and Computer Memory

2024

This chapter discusses ways that your code can be made to run faster.It roughly breaks into two very distinct topics: The theory of how fast an algorithm is in the abstract, independent of the details of the computer or the implementation.You don't need to know a whole lot about this subject -mostly just how to avoid a few potentially catastrophic errors. Various nitty-gritty performance optimizations, which mostly involve making good use of the computer's memory and cache.The first of these topics relates to figuring out which algorithms are fundamentally and theoretically better than others.The second topic is about how to eke out real-world performance gains for whatever abstract algorithm you are using. A Word of CautionDon Knuth, the computer scientist who invented the Big-O notation discussed in this chapter, is often quoted as saying that "premature optimization is the root of all evil."This chapter will discuss many techniques for making your code faster, but the first question to ask is whether you want to make it faster.Extra speed is nice, but if the optimizations will take a long time to implement, or if they will make your code difficult to understand and modify, it is often best to let well enough alone.In production systems that will be widely deployed obsessing about performance is sometimes justified.And certainly, if you're working on a large dataset, you need to make sure things scale gracefully.But, most of the time in data science work, there is usually something more important to do than shaving a few seconds off of the runtime.Personally, I usually I let man be the measure of things.If I find myself waiting around for a script to run, and I run that script with any regularity, it is usually worth refactoring to make it performant.The productivity hit from twiddling my thumbs is just too big to tolerate.But, if speed isn't getting in the way of my own ability to work, I focus more on making my code organized and flexible.

Ferrite Computer Memory Cores

National Institute of Standards and Technology (NIST) · 1960

Around 1960, George W. Reimherr at the National Bureau of Standards studied some of these ferrite computer memory cores to test a theory that changing the geometry of the core could increase the core's switching speed. A faster switching core would result in faster operating computer memory. Reimherr had standard memory cores ground into circular, square, and elongated rectangular shapes. After testing, Reimherr found no change in the switching speeds of cores of differing geometry. He determined that the switching speed of the cores was independent of their shapes.

Memory Management in Computer System

Glory V. Umoh · International Journal of Engineering Trends and Technology · 2014

Changing trends in technologies, notably cheaper and faster memory hierarchies, have made it worthwhile to revisit many hardware-oriented design decisions made in previous decades. Hardware-oriented designs, in which one uses special- purpose hardware to perform some dedicated function, are a response to a high cost of executing instructions out of memory; when caches are expensive, slowor in scarce supply, it is a perfectly reasonable to use hardware that do not compete with user applications for cache space and do not rely on the performance of the caches. In contrast, when the caches are large enough to withstand competition between the application and operating system, the cost of executing operating system functions out of the memory subsystem decreases significantly and software-oriented designs become manageable.
