Simultaneous personal sensing and data storage
First Claim
Patent Images
1. An apparatus comprising:
- a data acquisition subsystem to process a real-time data stream received from a sensor; and
a multi-port memory controller including an arbitration module, the multi-port memory controller to allow concurrent access to a memory by at least two ports, at least one of the ports to store real time data processed by the data acquisition subsystem in the memory, a dynamically configurable priority allocated to each of the ports for prioritizing access to the memory to minimize loss of the real-time data received from the data acquisition subsystem, the priority dependent on a state of the arbitration module, the state configurable remotely from a system accessible through a network communications port.

Abstract
A personal sensing device that may be used for storing personal data and sensed data arbitrates and prioritizes competing requests for memory access from sensing, wireless, and wired interfaces. The personal sensing device enables power efficiency with burst-writes to the memory at higher data rates then an incoming sensor data stream without risk of data loss. Sensing operations coordinated by reconfigurable control logic are partitioned from storage operations coordinated by a multi-port memory controller. The interface between the functional partitioning uses message passing, status/control registers and buffering to reduce or eliminate system interdependencies.

11. A method comprising:
-
processing a real time data stream received from a sensor by a data acquisition subsystem; and prioritizing requests to store the acquired real time data in a memory to allow concurrent access to the memory by at least two ports in a multi-port memory controller, the multi-port memory controller including an arbitration module, a dynamically configurable priority allocated to each of the ports for prioritizing access to the memory to minimize loss of the acquired real-time data received from the data acquisition subsystem, the priority dependent on a state of the arbitration module, the state configurable remotely from a system accessible through a network communications port. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
