Abstract

A portable data terminal including a multi-core processor having at least a first core and a second core, at least one illumination assembly and at least one imaging assembly and data storage means configured to store a plurality of program instructions, the program instructions including at least one one-dimensional decoder and at least one two-dimensional decoder.

Claims

1. A portable data terminal, comprising:

a multi-core processor having at least a first core and a second core;

at least one illumination assembly and at least one imaging assembly; and

data storage means configured to store a plurality of program instructions, the program instructions including at least one one-dimensional decoder and at least one two-dimensional decoder, wherein the program instructions stored in the data storage means further includes an image quality filter.

2. The portable data terminal of claim 1 wherein the data storage means further includes including at least one multi-port memory module having at least a first port and a second port, the at least one multi-port memory module being configured to receive output signals from the imaging assembly and communicate with the multi-core processor.

3. The portable data terminal of claim 1 further including a power supply, at least one system bus, a network interface, a display interface, a system bus, and a user input interface.

4. The portable data terminal of claim 1 further including at least one management module selected from the group consisting of a clock management module configured to dynamically vary the clock speed received by each respective core based on the workload of each core and a power management module configured to dynamically vary the voltage received by at least a portion of each core.

5. The portable data terminal of claim 1 wherein the first core of the multi-core processor executes the one-dimensional decoder and the second core executes the two-dimensional decoder.

6. The portable data terminal of claim 1 wherein the first core of the multi-core processor executes the image quality filter and the second core of the multi-core processor communicates with the network interface.
