First Claim
Patent Images
1. A data recorder comprising:
- a first memory element including read/write capability;
a second memory element including non-volatile memory; and
a controller for realizing memory management functions, wherein the controller writes selected data from the first memory element to the second memory element in response to a predetermined triggering event, the selected data including data that have been modified after a prior triggering event.

Abstract
A data recorder includes a first memory element including read/write capability, a second memory element including non-volatile memory and a controller for realizing memory management functions. The controller responds to a predetermined triggering event by writing selected data from the first memory element to the second memory element. The selected data include data units that have been modified after a prior triggering event.

20. A data recorder comprising:
-
an input/output switch coupled to an interconnection through which the data recorder can communicate with one or more first computing resources; a port coupled to an external input/output interface through which the data recorder can communicate with one or more second computing resources; a plurality of memory elements in communication with the input/output switch and the port; a controller in communication with the input/output switch, the port, and the plurality of memory elements, wherein the controller is configured to coordinate data flow via the input/output switch to exchange information between the data recorder and the one or more first computing resources, and wherein the controller is configured to coordinate data flow through the external input/output interface via the port to exchange information between the data recorder and the one or more second computing resources.
