Floating Data Meters

Relatively large numbers of acquired data are dynamically associated with a small number of meters for test and read-out purposes, thus allowing different kinds of data collected in association with each meter.

It is assumed the test system employs identical data meters such as five-digit meters used for usage analysis. In the past, each meter was incremented when a predetermined event occurred. In the present process, the same meter is incremented by any one of several predetermined events. The events are selected by entering a value into a "software data collection byte" (SDCB). The size of the SDCB determines the multiplier and resides in a CMOS memory.

Where the existing CMOS boards use only a four-bit-wide (one nibble) structure, the largest multiplier displayable in one nibble is nine. Applying this to two nibbles gives a multiplier of 99, etc.

The SDCB is changed by the user by entering a code corresponding to one of the l4 data meter locations (METERSEL). The numeric keyboard is used as the input device. A code is then entered to select a microcode incrementer module for the particular meter. The current "software feature flags" are used and changed in the same way, but are intended to select customer features. This ability to collect different pieces of data on the same meter allows collection of any kind of data from early development through manufacturing and marketing as well as reliability and customer data collection.
