Toshiba’s TC9040x ‘Donau’ series of processors are high-performance SoC devices are designed to simplify the design and reduce the component count of iDTVs, set-top boxes, and other consumer electronics products such as PVRs and combination hard disk/DVD recorder systems. These devices combine the company’s Media embedded Processor (MeP) architecture with a powerful 64-bit embedded RISC host processor to create multimedia SoCs with compute performances of up to 650MIPS (at 180MHz). The MeP architecture effectively frees the host processor from compute-intensive DVB and multimedia processing tasks and allows designers to choose cost-optimised solutions for DVB applications.
The Daewoo PVR uses the power of the ‘Donau’ SoC to enable genuine dual-stream functionality for simultaneous decode and output of dual video streams. The IC also provides three-stream audio processing to AAC, MPEG and AC-3 standards; audio post-processing including surround-sound and EQ functions; and a powerful multi-plane graphics engine with hardware accelerator.
