1.047GHz synthesizable 2-way VLIW general purpose DSP core has been developed by 1.2V 90nm CMOS technology. The key technology is to detect saturation from adder's inputs in an ALU and parallelize the saturation check with the adder operation. The proposed saturation anticipator circuit and the logic structure optimization improve DSP's clock frequency by 20.8%. The test chip also runs 0. 10muW/MHz...
We propose a new access scheme of synchronous dual-port (DP) SRAM that minimizes area of 8T-DP-cell and keeps cell stability. A priority row decoder circuit and shifted bit-line access scheme eliminates access conflict problem. Using 65nm CMOS technology (hp90), we fabricated 32KB DP-SRAM macros with the proposed scheme. We obtain 0.71mum2 8T-DP-cell, which cell size is 1.44times larger than 6T-single-port...
