We have started development of high-throughput single-flux-quantum (SFQ) microprocessors with the aim of higher throughput performance beyond CMOS microprocessors. All of the demonstrated microprocessors based on SFQ logic employed bit-serial processing. The bit-serial processing leads to reduction of complexity and ease of design, but it limits throughput. It is necessary to introduce bit-parallel processing for obtaining higher throughput beyond CMOS microprocessors. We can expect significant improvement in the throughput performance by introducing bit-parallel processing and a gate-level pipelined structure, in which pipeline processing is performed logic gate by logic gate. In this study, to realize bit-parallel SFQ microprocessors, we designed and evaluated a datapath that was the most complex circuit in a microprocessor. We integrated an arithmetic logic unit (ALU) and a register file to increase the operation frequency. We confirmed correct operation of addition and subtraction instructions and part of write-back operation of the register file up to approximately 30GHz. |
