How many memory locations (or memory cells) can be addressed by a 8086 microprocessor and why? (b) What is the largest (unsigned) hexadecimal number that can be stored in one memory location and why? (c) How many memory locations can be read in one read/write cycle and why? (d) Wha...
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 ...
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 ...
In order to be successful, a microprocessor must be able to run all of the programs (including operating systems and legacy programs) designed for that family of processors as fast as existing processors without costing more than existing processors. In addition, to be economically successful, a ...
A method for managing memory in a computer system utilizing Intel Corporation's method of segmentation, memory management and protection techniques. The method is directed toward loading all computer registers and segment descriptor tables from a table of prestored values in memory while operating in ...
