This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We have developed versatile timing systems, which are controlled by real-time signal processors. However, as a part of future developments of the complete set of spectrometer timing and signal processing electronics that could outperform existing state-of-the art timing system, we began to work on its concept and implementation. An essential part of it will be a modern dual-core digital signal processor (DSP) with 2400 Mflop. Initially it will run as a single 1200 Mflop core compatible with the existing software and will use existing Kernel, modified to support USB link to the host PC. This processor will supervise FPGAs, responsible for pulse-sequence generation, and will provide rapid "on-the-fly" pulse delay and width update without swallowing pulse sequences. It will also tightly synchronize all this activity with phase cycle and signal averaging. The existing system does this, but more advanced features, such as multi-pulse sequences, composite pulse generation, and TPPI will be better achieved with the enhanced system.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 我们开发了由实时信号处理器控制的多功能定时系统。然而，作为未来开发一套完整的光谱仪定时和信号处理电子设备的一部分，我们开始研究其概念和实现。它的一个重要组成部分将是一个现代化的双核数字信号处理器（DSP）与2400 Mflop。最初，它将作为一个与现有软件兼容的1200 Mflop内核运行，并将使用现有的内核，修改后支持USB连接到主机PC。 该处理器将监督负责脉冲序列生成的FPGA，并将提供快速的“即时”脉冲延迟和宽度更新，而不会吞下脉冲序列。它还将使所有这些活动与相位周期和信号平均紧密同步。现有的系统做到了这一点，但更先进的功能，如多脉冲序列，复合脉冲产生，和TPPI将更好地实现与增强系统。
