16. A method of decoding a bar code, comprising:
-
providing a PDT having a multi-port memory and a multi-core processor; capturing an image of a target; transferring image pixel data to one port of the multi-port memory; and executing program instructions stored in the multi-port memory on a first core of the multi-core processor so as to decode any one-dimensional bar code represented by the pixel data and on a second core of the multi-core processor so as to decode any two-dimensional bar code represented by the pixel data. - View Dependent Claims (17, 18, 20)

19. A system of capturing an image and decoding any bar code in the image, comprising:
-
a multi-core processor having at least a first core and a second core; a data storage means including at least one multi-port memory having at least a first port and a second port, the multi-port memory being in communication with at least one core of the multi-core processor; at least one illumination assembly and at least one imaging assembly, the imaging assembly being configured to transmit image pixel data to the multi-port memory; and wherein the data storage means comprises software including a one-dimensional decoder and a two-dimensional decoder that when executed causes each of the first and second cores of the multi-core processor to perform a respective method comprising; decoding any one-dimensional bar code represented by the pixel data; and decoding any two-dimensional bar code represented by the pixel data.
