The Mediator is a PCI implementation for
connecting PCI devices in Amiga computers, allowing expansion
of Amiga with all kinds of industry standard hardware products
like graphic, sound, network, USB, TV tuner, ISDN and MPEG-2
hardware decoder PCI cards.
Moreover, the Mediator PCI busboard is ready for SharkPPC
PCI cards based on the latest PowerPC G3 and G4 processors.
The minimum hardware configuration is: Amiga
1200 with Zorro IV busboard and 1240 turbo card with 16MB
The recommended configuration is: Amiga 1200 with Zorro IV
in the E/BOX tower case, any 68060 (or PPC with 68060) turbo
card with 64MB RAM, a SharkPPC G3/G4 card with 256MB SDRAM,
a Voodoo3 graphic card.
The Mediator PCI ZIV features:
4 PCI slots (PCI 2.1 compatible)
simultaneous use of up to four PCI cards fully assimilated
in the Amiga environment.
33MHz PCI clock (66MHz with SharkPPC G3/G4)
the PCI clock running at 33MHz, data transfers are executed
with the bandwidth of up to 132MB/s and up to 264MB/s for
32-bit PCI datapatch
Longword transfers are supported in all data transfer types:
PCI to Amiga, Amiga to PCI and PCI to PCI.
4GB PCI memory space
PCI ZIV allows access to the entire 4GB of the PCI memory
space. Access to the entire PCI memory space is executed through
the 8MB window in the A1200 memory space.
Busmastering/DMA in all PCI slots
PCI ZIV supports the busmastering mechanism in all its PCI
slots. The PCI cards in the busmaster mode can offer extremely
fast DMA access (up to 132MB/s) without any CPU load. Up to
four PCI busmaster cards may be used simultaneously in Mediator.
• SDRAM/SGRAM of PCI gfx card as
a DMA buffer
Mediator PCI ZIV uses part of the graphic card memory for
Amiga system needs. Thus, the entire system gains in effectiveness
as graphic card's SDRAM/SGRAM memory modules are about 10x
faster than FastRAM memory in Amiga turbo cards. With very
short access time in SDRAM/SGRAM, several PCI busmaster cards
may use this memory simultaneously. The PCI cards may then
rush at the data transfer rate of up to 132MB/s without any
CPU load whatsoever.
Address and data parity control support
and data parity are supported in all Mediator slots. Parity
support is necessary for using PCI cards like Sound Blaster
Audigy, Sound Blaster Live! or ForteMedia FM801-based PCI
Interrupt controller (4 lines to each PCI card)
The Mediator Interrupt Controller manages four independent
PCI interrupt lines.
• PCI and Zorro
Mediator PCI ZIV enables
simultaneous operation of PCI cards in its slots and Zorro
II/IV cards installed in the Zorro IV busboard.
PCI ZIV is compatible with all the major A1200 turbo card
Mediator PCI ZIV is designed for the following turbo cards:
Blizzard PPC/060, Blizzard PPC/040, Blizzard 1260, Apollo
1260, Blizzard 1240 and Apollo 1240.
Mediator PCI ZIV, PCI cards in its slots and Zorro II cards
in Zorro IV busboard slots fit perfectly in the following
Power Tower, Winner Tower, Infinitiv Tower, EZ-Z4 Tower.
Installation is very easy, see Mediator
PCI ZIV Quick Installation Guide.
