The Wave Walker (PMC, VME, CPCI) occupies 16k of PCI memory space accessed from a single base address register.  The host processor has direct access to all control registers, including the receiver input attenuator level, dither noise power level, receiver sample rate, downconverter (HSP50214) configuration space, transmitter sample rate, upconverter (HSP50215) configuration space, local command/status, and transceiver data flow control.  The PCI interface includes an interrupt to alert the host of an error condition or data service request.

Programming the Wave Walker (PMC, VME, CPCI) is simplified by a configuration tool that automates the process of computing register values based on the desired performance characteristics of the transceiver.  The user enters configuration information through a series of guided spreadsheets that describe the purpose of each control register, setting options, and default values.  The spreadsheets also perform error checking to eliminate configuration conflicts and graphically display key performance parameters in architecture block diagrams and frequency response plots.  The configuration tool generates a file containing the complete memory map that can be easily uploaded from the host.
