Embodiment Construction

[0036] It should be noted that any reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0037] Details and other pertinent information regarding the assignment of priorities, designation of MITs and LITs, and determination of budgets can be found in U.S. Patent Application Serial Nos. 10 / 169,346 and 10 / 294,530, both of which Both are hereby incorporated by reference in their entirety. It is worth noting that in these patent applications, the concept of priority used is the meaning of operating system priority, not the meaning of relative importance. In the scheduling algorithm used, the previous priority is usually assigned according to the budget period. Som...

Abstract

A method (60) for controlling multiple tasks in a real-time operating system (110, 170) assigns priorities to two or more tasks (114, 115; 174, 175). A first task (114; 174) is assigned to be a More Important Task. A second task (115; 175) is assigned to be a Less Important Task. Each task is explicitly informed of its budget allocations. A Guaranteed Budget Margin is then allocated to the More Important Task along with a More Important Guaranteed Budget. A Less Important Guaranteed Budget is also allocated to the Less Important Task. At some point during execution, the higher priority or More Important Task (114; 174) may then determine that the More Important Task no longer requires the Guaranteed Budget Margin, in which case, a Conditionally Guaranteed Budget Margin is then allocated to the Less Important Task (115; 175).

Description

technical field [0001] The present invention relates generally to methods and apparatus for managing resources in operating systems, and more particularly to methods and apparatus for managing resources in real-time functioning operating systems. Background technique [0002] High Volume Electronics (HVE) consumer systems such as digital TVs, digital-enhanced analog TVs and set-top boxes (STBs) are often part of product families that need to be open and flexible while remaining cost-effective and robust . Such systems have properties that are characteristic of the hard real-time domain. [0003] Since openness and flexibility are typical features of software-based systems, a significant portion of multimedia processing in HVE user systems is expected to become implemented in software, in addition to existing software implementations for control and services. Component technology is considered as the fundamental technology for open and flexible systems. note that since HVE...
