Abstract

An alternative approach to coping with the ever increasing demand for faster communications hardware is to design modems that are capable of operating its speeds at a higher data rate than a speed required for a single port of the standard communication rate for that modem. Basically, by utilizing a resource manager, that directs the data in and out of the various portions of the modem in an orderly manner, keeping track of which of the ports is being operated at any given point in time, a standard single port modem can be reconfigured, for example, at an over clocked rate, to manipulate the data input and output of a modem.

Claims (9)

1 A multicarrier multiport modem comprising a plurality of ports and one or more resource managers that configure the ports to support a plurality of modes of operation, wherein a first mode of operation supports 1 port of Asymmetric Digital Subscriber Line (ADSL) operating concurrently with 1 port of powerline or wireless communications, and a second mode of operation supports 1 port of Very High Speed Digital Subscriber Line (VDSL) operating concurrently with 1 port of powerline or wireless communications.
2. The modem of claim 1, further comprising a Fast Fourier Transform Media Access Controller (FFT MAC) engine, wherein in the first mode of operation the one or more resource managers configure the FFT MAC engine to operate as at least one 512 point Fast Fourier Transform (FFT), and wherein in the second mode of operation the one or more resource managers configure the FFT MAC engine to operate as at least one 4096 point FFT.
3. The modem of claim 1, further comprising a Fast Fourier Transform Media Access Controller (FFT MAC) engine, wherein in the first mode of operation the one or more resource managers configure the FFT MAC engine to operate as at least one 512 point Inverse Fast Fourier transform (IFFT) , and wherein in the second mode of operation the one or more resource managers configure the FFT MAC engine to operate as at least one 4096 point IFFT.
4. A method for a multicarrier multiport modem, that includes a plurality of ports, to support a plurality of modes of operation, comprising:

configuring the ports to support the plurality of modes of operation, wherein a first mode of operation supports 1 port of Asymmetric Digital Subscriber Line (ADSL) operating concurrently with 1 port of powerline or wireless communications, and a second mode of operation supports 1 port of Very High Speed Digital Subscriber Line (VDSL) operating concurrently with 1 port of powerline or wireless communications.
5. The method of claim 4, further comprising configuring, for the first mode of operation, a Fast Fourier Transform Media Access Controller (FFT MAC) engine to operate as at least one 512 point Fast Fourier Transform (FFT), and, for the second mode of operation, the FFT MAC engine to operate as at least one 4096 point FFT.
6. The method of claim 4, further comprising configuring, for the first mode of operation, a Fast Fourier Transform Media Access Controller (FFT MAC) engine to operate as at least one 512 point Inverse Fast Fourier Transform (IFFT), and, for the second mode of operation, the FFT MAC engine to operate as at least one 4096 point IFFT.
7. A multicarrier multiport modem, that includes a plurality of ports, that support a plurality of modes of operation, comprising:

means for communication; and means for configuring the ports to support the plurality of modes of operation, wherein a first mode of operation supports 1 port of Asymmetric Digital Subscriber Line (ADSL) operating concurrently with 1 port of powerline or wireless communications, and a second mode of operation supports 1 port of Very High Speed Digital Subscriber Line (VDSL) operating concurrently with I port of powerline or wireless communications.
8. The modem of claim 7, further comprising configuring, for the first mode of operation, a Fast Fourier Transform Media Access Controller (FFT MAC) engine to operate as at least one 512 point Fast Fourier Transform (FFT), and, for the second mode of operation, the FFT MAC engine to operate as at least one 4096 point FFT.
9. The modem of claim 7, further comprising configuring, for the first mode of operation, a Fast Fourier Transform Media Access Controller (FFT MAC) engine to operate as at least one 512 point Inverse Fast Fourier Transform (IFFT), and, for the second mode of operation, the FFT MAC engine to operate as at least one 4096 point IFFT.
