A multicore processor is achieved by a processor assembly, comprising a first processor having a first core and at least a first and a second unit, each being selected from the group of vector execution units, memory units and accelerators, said first core and first and second units being interconnected by a first network, and a second processor having a second core wherein the first core is arranged to enable the second core to control at least one of the units in the first processor. Each processors generally comprises a combination of execution units, memory units and accelerators, which may be controlled and/or accessed by units in the other processor.
