1.2 MEMORY
1.2.1 System SRAM Interface
The system SRAM interface controls access to optional external SRAM, which can be used for RISC
code, stack, and data. The SRAM bus supports four independent address spaces, each having programmable bus
width and wait states. The interface can support not only SRAM, but also
ROM/EPROM and memory-mapped I/O ports for standalone applications are supported.
1.2.2 DRAM Memory Interface
The Vibratto II provides a glueless 16-bit interface to DRAM memory devices used as video memory
for a DVD player. The maximum amount of memory supported is 16 MB of Synchronous DRAM (SDRAM).
The memory interface is configurable in depth to support 128-Mb addressing. The memory interface controls
access to both external SDRAM or EDO memories, which can be the sole unified external read/write memory
acting as program and data memory as well as various decoding and display buffers.
1.3 FRONT PANEL
The front panel is based around an Futaba VFD and a common front panel controller chip, (uPT6311).
The ES66x8 controls the uPT6311 using several control signals, (clock, data, chip select). The infrared remote
control signal is passed directly to the ES66x8 for decoding.
1.4 REAR PANEL
A typical rear panel is included in the reference design. This rear panel supports:
- six channel and two channel audio outputs
- Optical and coax S/PDIF outputs.
- Composite, S-Video, and SCART outputs
The six-video signals used to provide CVBS, S-Video, and RGB are generated by the ES66x8?s internal video
DAC. The video signals are buffered by external circuitry.

Six channel audio output by the ES66x8 in the form of three IS (or similar) data streams. The S/PDIF serial
stream is also generated by the ES66x8 output by the rear panel. A six channel audio DAC are used for six
channel audio output with ES66x8, and similarly one Audio DAC is used for two channel audio output with
ES66x8.
