If a Hankel matrix H is constituted by coefficients of x-i in a(x)/f(x), then H-1=B[f, b] were a(x)b(x)=1 mod f(x), and B is a Bezoutiant. We show this fact, and apply it to a calculation of a dual base in GH(pn).

A 64-bit architecture for an embedded processor targeted for next-generation digital consumer products has been developed. It has dual-mode instruction sets and is optimized for high multimedia performance, provided by SIMD/floating-point vector instructions in 32-bit length ISA, and small code size, provided by a conventional 16-bit length ISA. Large register files, (6464b and 6432b), a split-branch mechanism, and virtual cache are also adopted in the architecture. A 714MIPS/9.6 GOPS/400 MHz processor core with the 64-bit architecture and a system LSI containing the core are developed using 0.15-µm technology. The LSI includes a 3.2 GB/sec high-bandwidth on-chip bus, a high-speed DRAM interface, a SRAM/Flash/ROM/Multiplexed-bus interface, and a 66 MHz PCI interface that provide the performance required for next-generation multimedia applications.
