memory.
Supports up to 128 MBytes system memory
in 4 banks and as little as MBytes.
Supports 4MBytes, 8MBites, 16MBites,
32MBites single-sided and double-sided
DRAM SIMMs.
Four quad-word write buffers for CPU to
DRAM and PCI to DRAM cycles.
Four 4-word read buffers for PCI masters.
Supports Fast Page Mode & EDO DRAMs.
Programmable timing for DRAM parameters
including CAS pulse width, CAS pre-charge
time, and RAS to CAS delay.
60, 70, 80 & 100ns DRAM speeds.
Memory hole size of 1 MByte to 8 MBytes
supported for PCI/ISA buses.
Hidden refresh.
To check if your memory device is supported by
the STPC, please refer to

YUV to RGB).
Programmable window size.
Chroma and colour keying allowing video
overlay.
Programmable two tap filter with gamma cor-
rection or three tap flicker filter.
Progressive to interlaced scan converter.
Video Input port
Decodes video inputs in ITU-R 601/656 com-
patible formats.
Optional 2:1 decimator
Stores captured video in off setting area of
the onboard frame buffer.
Video pass through to the onboard PAL/
NTSC encoder for full screen video images.
HSYNC and B/T generation or lock onto
external video timing source.
PCI Controller
Integrated PCI arbitration interface able to
directly manage up to 3 PCI masters at a
time.
Translation of PCI cycles to ISA bus.
Translation of ISA master initiated cycle to
PCI.
Support for burst read/write from PCI master.
The PCI clock runs at a third or half CPU
clock speed.
