Abstract
A communication stack for software-hardware co-execution on heterogeneous computing systems with processors and reconfigurable logic, in one aspect, may comprise a crossbar operable to connect hardware user code and functioning as a platform independent communication layer. A physical interface interfaces to the reconfigurable logic. A physical interface bridge is connected to the cross and the physical interface. The physical interface bridge connects the crossbar and the physical interface via a platform specific translation layer specific to the reconfigurable logic. The crossbar, the physical interface, and the physical interface bridge may be instantiated in response to the hardware user code being generated, the crossbar instantiated with associated parameters comprising one or more routes and associated data widths. The hardware user code is assigned a unique virtual route in the crossbar.
