An improved memory segmentation system in a microprocessor, for generating a segment descriptor based on a segment selector, comprises an associative descriptor cache 570 to retain previously fetched, unscrambled, and tested descriptors for subsequent access by the same selectors. If on a memory ...
An application that needs to isolate small chunks of memory must place each chunk in its own page, leading to excessive internal fragmentation. With segmentation, instead of one contiguous virtual address space per process, we can have multiple variable sized virtual spaces, each mapped, managed, ...
In the middle of the process's address space, there is a region is reserved for shared objects. When a new process is created, the process manager first maps the two segments from the executable into memory. It then decodes the program's ELF header. If the program header indicates that ...
In the case of the 8086, segmentation let Intel's designers extend the maximum addressable memory from 64K to one megabyte. Gee, that sounds good. Why is everyone complaining? Well, a little history lesson is in order to understand what went wrong. In 1976, when Intel began designing the ...
Different memory management techniques include paging, segmentation, virtual memory, garbage collection and memory compression. For example, paging divides physical memory into fixed-size units or pages and maps them to logical units, called frames. Paging can improve memory use and protection. It can...
China Flash Memory Industry Segmentation Flash memory is a non-volatile electronic computer memory storage medium that can be erased and reprogrammed electrically. Flash memory is widely used in embedded systems to store data and code. Unlike traditional hard drives, flash memory can store data even...

With segmentation, instead of one contiguous virtual address space per process, we can have multiple variable sizedvirtual spaces, each mapped, managed, and shared independently. Segmentation-based addressing is a two step process involving application code and processor hardware: code loads a segment ...
1. A method, comprising: mapping addresses in a single address space to resources within a set of multiple programmable units integrated within a processor, the single address space including addresses for different ones of the resources in different ones of the multiple programmable units; and prov...
