Multithreaded processor core with hardware-assisted task scheduling

A method comprising:

• requesting, by a hardware thread of a multithreaded processor core, work from a task manager;
• reading, by the task manager, a task descriptor from a hardware queue;
• and
• issuing, by the task manager, a task described by the task descriptor.

A system comprising:

• a processor including:
• a first hardware thread;
• a second hardware thread;
• and
• a task manager to issue a task to the first hardware thread, the task manager including a hardware task queue in which to store a plurality of task descriptors, each of the task descriptors to represent one of a single task, a collection of iterative tasks, and a linked list of tasks;
• and
• a system memory coupled to the processor, wherein the first hardware thread and the second hardware thread have a coherent view of the system memory.
