Abstract
A method and apparatus for dynamic partial reconfiguration on an array of processors. The method includes the steps of verifying if a processor is ready for dynamic partial reconfiguration to begin, deciding the degree of dynamic partial reconfiguration, including the number and identity of all processors to be modified, executing native machine code in the port of a processing device, and modifying a segment of the internal memory of said single processing device. Additional embodiments allow modification of multiple processors in the array, including the modification of all processors on a die or system. The apparatus includes a processor array having a first group of processors connected together for performing a first task, and a second group of processors connected together for performing a second task with at least one processor connected to said first group of processors and said second group of processors for facilitating communications between said first group of processors and said second group of processors without participating in said first task and said second task. In an embodiment of the apparatus, this one processor dynamically reconfigures the array. Additional embodiments allow additional processors to aid in the reconfiguration.
