Most of the implementations of boundary scan chains are of fixed length, typically hundreds or thousands. Because the whole chain is scanned every time, many clock cycles are wasted when only a small part of it is concerned. In this paper, a novel structure of configurable boundary scan chain is proposed. Its length and content can be reconfigured without interrupting the chip's functionality. Experimental result shows that the maximum frequency can be as high as 510.4MHz for a full-configurable chain with 512 cells, under 32 nm process, which is 15.7x better than the intuitive method. The proposed structure has been applied to a processor prototype design, and is expected to meet requirements of different applications.

To solve the problem of deterioration of system performance for the analog front-end(AFE) non-idealities, such as Carrier Frequency Offset(CFO), IQ mismatch and Sampling Frequency Offset(SFO) in OFDM system, this paper proposes a novel joint estimation and compensation algorithm, which estimates and compensates CFO and IQ imbalance in time domain, while compensates Residual Carrier Frequency Offset(RCFO) and SFO in frequency domain. Compared with the traditional algorithms, the proposed scheme uses fewer data supporting resources to improve the estimation accuracy by introducing an iterative updating scheme. Significant non-idealities introduced, the proposed scheme is also able to achieve a low bit error rate.
We theoretically and numerically analyze the multi-carriers generation scheme based on only integrated IQ modulator. Flat and stable 11 carriers are obtained and 112Gb/s PM-QPSK experiment over a single subcarrier has...
