Teras DSP 1 V, 50 MHz, 16-bit dibangunkan menggunakan perpustakaan Dwi Vt 0.25-µm, SRAM dan ROM Mask yang disesuaikan untuk operasi 1 V. Kelajuan teras dipertingkatkan sebanyak 41% menggunakan saluran paip pelaksanaan MAC dan 2 peringkat alternatif. Penukar naik voltan 1.0 V hingga 1.5 V dengan kecekapan kuasa 59% dan penukar aras 450 ps 1 V hingga 2.5 V telah dilaksanakan. Kaedah anggaran kelewatan wayar panjang baharu telah meningkatkan sintesis. Penggunaan kuasa yang diukur pada 0.9 V ialah 8.7 mW, iaitu 40% kurang daripada kuasa perpustakaan biasa pada 1.3 V, apabila perisian tegar PSI-CELP CODEC dijalankan pada 40 MHz.

Abstract: An 1 V, 50 MHz, 16-bit DSP core was developed using a 0.25-µm Dual Vt library, SRAM, and Mask ROM tailored for 1 V operation. The core speed was 41% enhanced using an alternate MAC and 2-stage execution pipeline. A 1.0 V to 1.5 V voltage up converter with 59% power efficiency and a 450 ps 1 V to 2.5 V level converter were implemented. An new long wire delay estimation method enhanced the synthesis. The measured power consumption at 0.9 V was 8.7 mW, which was 40% less than the power of the normal library's at 1.3 V, when the PSI-CELP CODEC firmware was run at 40 MHz.
