N2 - To accelerate the data acquisition system (DAQ), which was reported in NSS 2004[1], the authors improved the Main ADC Modules in the DAQ. The new Main ADC Module has 8 input channels. Each channel consists of analog circuits for pulse shaping, a high-speed ADC (14bit 125MSPS), and a highpower Digital Signal Processor (DSP: 8000MIPS). Shaped input signals are digitized with the ADC and analyzed by the DSP to calculate the energy data. For fast data transfer, the energy data from every four channels are bundled and stored into a large Dual Port Memory (DPM: 2MByte). The bundled data are read out to a PC through VME-BUS. By combining high-speed ADCs, high-power DSPs and large DPMs, high speed and high density DAQ was constructed.
