A digital logic device is disclosed that includes registers, SRAM, DRAM, and a processor configured to store in the registers an initial portion of a first response data to a command, and store in the SRAM the first response data. The processor is further configured to store in a lookup table the memory location and size of the first response data in the SRAM, store in the DRAM additional response data, and store in the lookup table the memory location and size of the additional response data in the DRAM. The processor is configured to receive the command from a host device, retrieve the first response data from the registers or the SRAM, and send the first response data to the host. If the command includes additional response data, the processor is configured to concurrently retrieve the additional response data from DRAM and send the additional response data to the host.

Serial device emulator using two memory levels with dynamic and configurable response

A method and apparatus for testing components is disclosed. The method involves a system operating to collect data in a certain frequency range, and utilizing signals outside that frequency range to test the system during operation. Such testing may be conducted on a not-to-interfere basis, thereby allowing for testing during operation of systems in continuous use.

Method and apparatus for testing components

A system and method for monitoring interaction between a stationary object and multiple mobile units are described. Positioning data is received from one or more mobile units. Positioning data is processed to retrieve a position of each mobile unit. Finally, one or more warning devices are activated based on a predetermined set of criteria related to the position.
