1. A graphical code reader, comprising:
- an imager that provides image data corresponding to a two-dimensional image of a graphical code, wherein the graphical code comprises graphical code data;
a processor;
memory in electronic communication with the processor;
data processing instructions in the memory;
an imager interface that facilitates transfer of the image data from the imager to the memory;
a control bus interface in the imager interface, wherein the control bus interface is in electronic communication with a first portion of a control bus and with a second portion of the control bus, wherein the first portion of the control bus couples the processor to the control bus interface, and wherein the second portion of the control bus couples the control bus interface to the memory;
a data bus interface in the imager interface, wherein the data bus interface is in electronic communication with a data bus that couples the processor to the memory; and
address generation instructions in the memory that are executable by the processor to set the imager interface to an active mode, generate an address in the memory for storing the image data, provide a read signal on the first portion of the control bus, and provide an address signal on an address bus, wherein in response to the read signal on the first portion of the control bus the control bus interface provides a write signal on the second portion of the control bus.

Abstract
A graphical code reader includes an imager that provides image data corresponding to a two-dimensional image of a graphical code. The graphical code reader also includes a processor and memory in electronic communication with the processor. The graphical code reader also includes an imager interface. The imager interface facilitates transfer of the image data from the imager to the memory. The processor does not receive the image data as the image data is being transferred from the imager to the memory. The imager interface comprises a control bus interface, an address bus interface, and a data bus interface.
