ABSTRACT:
Systems and methods for halting the execution of instructions in a microprocessor are disclosed. The halt instruction may have an operand which allows a programmer to specify which clock of a system is to be utilized in conjunction with the halt instruction. A specified number of clock cycles may then be counted using the clock identified in the instruction, after which dispatch of instructions may resume. These system and methods may also allow the execution of instructions to be halted with respect to one or more of a multiplicity of threads within a microprocessor while allowing the continued execution of instructions associated with the remaining threads.
