Thread sequencing for multi-threaded processor with instruction cache

摘要

Execution of the first thread of a new program is prioritized ahead of older threads for a previously running program. The new program is invoked during the execution of a thread of the previous program. The first thread of the program is prioritized ahead of the remaining threads of the previous program. In an embodiment of the invention, additional threads of the new program are also prioritized ahead of the older threads. A thread's context may include a table of constant values that can be referenced by each program and are shared by multiple threads. Changing the values in a constant table for a new thread is time intensive. To avoid changes to the constant table (and thereby save time), a higher priority status is conferred to the first thread that follows a change to the constant table.
