A 0.18 /spl mu/m CMOS SoC of a front-end hardware platform for DVD-multi recorders

This work presents a 0.18 /spl mu/m CMOS system on a chip (SoC) that is a hardware platform for the front-end of DVD-multi recorders (FESOC). It has one 32 bit RISC CPU and one 16 bit DSP as well as most of the necessary components for DVD recorders, except for an analog front end (AFE) and some memories. The necessary building blocks are a partial response channel maximum likelihood detector (PRML), a servo signal processor (SERVO), write strategy controller (WSC), a data processor (DP), an AT-attachment packet interface (ATAPI), and a micro computer unit (MCU). Using a three-layered bus architecture enables this FESOC to work well with a 16 bit-wide bus at 67 MHz for 8/spl times/ DVD operation, and to be implemented with a short development time. The FESOC is fabricated in 0.18 /spl mu/m 1-poly 5-metal CMOS technology. It contains 8.4 million transistors in a 46 mm/sup 2/ die and consumes 1.4 W with a channel clock of 209.28 MHz in 8/spl times/ operation mode.

DVD system software simulator

Software tool is developed for the optical disk drive functions simulation. Disks of DVD-ROM/R/RW/RAM and CD-ROM/R/RW formats are supported. Modeling of pick-up optics with diffraction calculation and servo loops dynamics is included.
