Unformatted text preview: non-blocking or not. A. TSI is non-blocking. Given any kind of input-output connection requirements, we can write all slot data into the buffer and read out all of them to the output in each cycle. As a result, each cycle receives N slot data and delivers N slot data, there is no blocking. Question 3. The following architecture is a combination of TSI and crossbar, where each blue arrow is a TDM link. Discuss if it is possible to use a crossbar architecture plus multiplexers/de-multiplexers to build a switch and avoid the use of TSI? If yes, suppose each TDM link has four time slots (four user channels), draw a figure to show your design. A. Yes, it is possible. The solution is 1. Replace each TSI at input with a demultiplexer 2. Replace each TSI as output with a multiplexer 3. Replace the NxN crossbar with a NM x NM crossbar, where M is the number of slots we have for TDM. In the example, we use a 16x16 crossbar....
