Description
For example, FIG. 3 illustrates an exemplary embodiment of a multimode multicarrier modem that is capable of supporting multiple ports simultaneously. In particular, as previously discussed, the multimode multicarrier modem 100 comprises an interface block 200, a framer block 300, a transformation block 400, an equalizer block 500 and a resource manager 600, interconnected by links 5. In this exemplary embodiment, the framer 300 comprises a framer CRC scrambler 310, an inverse-framer CRC descrambler 320, a Reed Solomon Coder 330, a Reed-Solomon Decoder 340, an interleaver 350 and a deinterleaver 360. The transformation block 400 comprises a QAM encoder trellis 410, a QAM decoder trellis 420, an equalizer 430, a DMT modulator (IFFT) 440 and a DMT demodulator (FFT/FDQ) 450. The equalizer block 500 comprises an interpolator and echo canceller 510 and an echo cancellation and time domain equalizer (TDQ) 520.
Thus, for example, in the exemplary embodiment illustrated in FIG. 3, a multicarrier modem is capable of, for example, allocating 32 Mbps to be used to support 4 ports of 8 Mbps ADSL or 1 port of 32 Mbps VDSL. This is accomplished by changing the operation of the resource manager 600. For example, the modifications to the resource manager 600 can be a software command that regulates the operation of the various engines and directs and maintains the input and data output from the resource manager 600. With this exemplary embodiment, the number of transistors required to implement a multi-port solution and the ability, through software commands, to configure the silicon to operate as either a multiport ADSL or, for example, a VDSL solution, is provided. Furthermore, it is also possible to configure the silicon to operate in a combination of ADSL and VDSL ports. In the example illustrated in FIG. 3, where a 32 Mbps engine is used in the example, the engine can be reconfigured to support one 8 Mbps ADSL port and two 12 Mbps VDSL ports.
FIG. 8 illustrates an exemplary method of operation of a resource manager. In particular, control begins in step S100 and continues to step S110. In step S110, the service requirements are established. For example, the modem can be configured to operate in a single, such as high speed mode, a multi-mode configuration, or any combination thereof. Next, in step S120, for each service type, the operation of resource manager is determined. Then, in step S130, for each resource manager, the frame boundaries are determined in step S140. Control then continues to step S150.
In step S1150, the memory, or buffers, are divided based on the frame boundaries. Next, in step S160, the addressing of the resource manager(s) are configured to correctly route data between the various functional blocks. Control then continues to step S170 where the control sequence ends.
