VHDL design of digital time switch
The digital time switch is a device that performs switching of time-division multiplexed, pulse code modulated (TDM-PCM) data. The switching functions performed are space division and time division multiplexed data. Switching in time refers to the process of interchanging the information correspondi...

| 總結: | The digital time switch is a device that performs switching of time-division multiplexed, pulse code modulated (TDM-PCM) data. The switching functions performed are space division and time division multiplexed data. Switching in time refers to the process of interchanging the information corresponding to two subscribers.Space division switching is achieved by switching informations between two PCM links while time division is achieved by switching the information between different time slots within the same PCM link or channel.The circuitry or design is prototyped using an field programmable gate array (FPGA). The design of the circuit in the FPGA is a venture in Very high speed IC Hardware Description Language (VHDL) that uses a programming language for the input design to the FPGA.The integral element of this thesis is to create a VHDL code design that will be used to program the FPGA to achieve the function of time and space division multiplexed switching. |
