WebJul 22, 2024 · A Microprocessor is an important part of a computer architecture without which you will not be able to perform anything on your computer. It is a programmable device that takes in input performs some arithmetic and logical operations over it and produces the desired output. In simple words, a Microprocessor is a digital device on a … Web7.4 Task Gate Descriptor. A task gate descriptor provides an indirect, protected reference to a TSS. Figure 7-4 illustrates the format of a task gate. The SELECTOR field of a task gate must refer to a TSS descriptor. The value of the RPL in this selector is not used by the processor. The DPL field of a task gate controls the right to use the ...

WebThe Global Descriptor Table (GDT) is a data structure used by Intel x86-family processors … The task state segment (TSS) is a structure on x86-based computers which holds information about a task. It is used by the operating system kernel for task management. Specifically, the following information is stored in the TSS: Processor register stateI/O port permissionsInner-level stack … See more The TSS may reside anywhere in memory. A segment register called the task register (TR) holds a segment selector that points to a valid TSS segment descriptor which resides in the GDT (a TSS descriptor may not reside in the See more The TSS contains a 16-bit pointer to I/O port permissions bitmap for the current task. This bitmap, usually set up by the operating system when a task is started, specifies individual … See more The TSS contains 6 fields for specifying the new stack pointer when a privilege level change happens. The field SS0 contains the stack segment selector for CPL=0, and the field ESP0/RSP0 contains the new ESP/RSP value for CPL=0. When an interrupt happens in … See more The TR register is a 16-bit register which holds a segment selector for the TSS. It may be loaded through the LTR instruction. LTR is a privileged … See more The TSS may contain saved values of all the x86 registers. This is used for task switching. The operating system may load the TSS with the values of the registers that the new task needs and after executing a hardware task switch (such as with an IRET … See more This is a 16-bit selector which allows linking this TSS with the previous one.
