System and method for halting processing cores in a multicore system

A method comprising:

• in a multicore computing device that includes a memory and a processor coupled to the memory, the processor including a plurality of cores and a multiple input multiple output (MIMO) block that is coupled to the plurality of cores and that comprises a timeout register:
• receiving, by a HALT IP of the MIMO block, a halt request from a first core of the plurality of cores;
• transmitting, by the HALT IP of the MIMO block, a core-halt request to one or more other cores of the plurality of cores other than the first core, to halt execution of the one or more other cores;
• and
• permitting, by the HALT IP of the MIMO block, the first core continue execution and to lock with a shared resource,
• wherein the halt request comprises a timeout duration and a list of the one or more other cores and
• wherein the MIMO block is configured to set the timeout register based on the timeout duration specified in the halt request.
