Command translation of burst commands is described. A slave processor local bus ("PLB") bridge, part of a processor block core embedded in a host IC, has a data size threshold to allow access to a crossbar switch device. A master device, coupled to the slave PLB bridge, has any of a plurality of command bus widths. A burst command is issued via a command bus, having a command bus width of the plurality, from the master device for the slave PLB bridge. The burst command is converted to a native bus width of the slave processor logic block if the command bus width is not equal to the native bus width. The burst command is translated if execution of the burst command will exceed the data size threshold and passed without the translating if the execution of the burst command will not exceed the data size threshold.
