I see you know Freescale MPC series very well. Habib.

Strange that obviously very few people knows what are the main fonctional components of a voice/data core switch (like in a PBX). Time Solt Assigner is one of those. I'm beeing implement a TSAC in FPGA. Thanks, Habib.

You can extend the instruction to do TSA. For example, the BM32 opcode 0x30 is extended instruction. There should be some unimplemented opcode for TDM extensions. In the worst case, we have to steal another opcode for that, if we need to make it binary compatible. TDM/TSA should take no more than 5% of XC6SLX4. BM32 might take 50% to 70%. There should be more than 20% left for everything else. Adding three SSR, then you are in business.
