Assignee: GOWIN SEMICONDUCTOR CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 0:
1. A system containing a field-programmable gate array (“FPGA”) configured to process digital information, comprising:
a metering instrument containing at least one display for visually displaying a number and configured to record amount of measurable substance within a predefined time period;
a camera coupled to the metering instrument and configured to capture an image of the number representing at least a portion of the amount of measurable substance;
a recognition module operable to generate a counter value in response to the image and coordinates utilized for minimizing image distortion; and
an FPGA configured to facilitate removably coupling to a localization module via a localization-to-recognition communication for supplying coordinates from the FPGA to the recognition module via a recognition interface block, the FPGA configured to have,
a first portion of FPGA programmed to perform an interface function for facilitating removably coupling to the camera via a camera-to-localization communication for receiving images from the camera;
a second portion of FPGA programmed to perform a multi-task function for detecting at least one digit from the image and an angle prediction;
a third portion of FPGA programmed to perform a control function for generating a set of coordinates at least partially based the angle prediction;
a fourth portion of FPGA configured to perform a forwarding function for sending the set of coordinates to a recognition module via a localization-to-recognition bus.
