A software development technique is provided using target system virtualization software simulating behaviour of a target system. A target device driver running on a host system issues memory access commands to the target system virtualization software rather than to a memory interface unit of the host system. The memory interface unit may be an SRAM (Static Random Access Memory) interface. The target system may be an EGPRS (Enhanced General Packet Radio Service) modem.

Memory access to virtual target device

A WLAN (Wireless Local Area Network) transmitter or another data communications apparatus is provided that includes a transmission section that is configured to generate signals to be transmitted, and a control section that is connected to the transmission section to control the transmission section dependent on at least two transmission parameters. The control section comprises a state transition controller that is configured to step through a plurality of predefined control states. The control section is configured to apply different transmission parameter modification mechanisms in different control states. The state transition controller is configured to determine the respective next control states based on transmission success and failure statistics.
