JTAG Interface using a STM32F103

I want to develop a JTAG interface using STM32F103. One way is to use GPIO to drive/read the signals, another way is to use SPI, but unfortunately TMS signal is not present. Is there a way to use SPI and simulate a TMS sincronous with SPI clock ? Any other solution? Any suggestion is well come.

best regards
