	Resumo
	This paper describes a real-time pulse height analysis diagnostic for feedback control of the TCV plasma. The implementation of this diagnostic is based on a new generation Xray detector with high resolution and count rate, an on-site developed VME intelligent module, with parallel processing capabilities provided by four Digital Signal Processors, and several digital signal processing algorithms. Results show that a value of the electron temperature (Te) is calculated in about 100 ms, allowing to obtain a twenty Te profile during a TCV discharge. The time resolution might be increased by improving the X-ray detecting system and/or the processing procedures.
