Let’s start building a Raw board • Single Raw processor • 14 I/O ports Raw
Add a memory sub-system • 2 Xilinx XC2V3000 FPGAs for memory controllers • Separate memory controller on each port • 512 MB PC133 SDRAM DIMM for each controller • 128 MB address space for each tile by default MC0 512 MB DIMM Raw 512 MB DIMM MC1 512 MB DIMM 512 MB DIMM
Add a PCI sub-system • Xilinx XC2V3000 FPGA for PCI controller • Three 64-bit / 66 MHz PCI slots 64-bit PCI slot 64-bit PCI slot 64-bit PCI slot PCI MC0 512 MB DIMM Raw 512 MB DIMM MC1 512 MB DIMM 512 MB DIMM
Host PC with SLAAC-1V CONF Add a PCI sub-system • Xilinx XC2V3000 FPGA for PCI controller • Three 64-bit / 66 MHz PCI slots 64-bit PCI slot 64-bit PCI slot 64-bit PCI slot PCI MC0 512 MB DIMM Raw 512 MB DIMM MC1 512 MB DIMM 512 MB DIMM • Xilinx XC2V1000 FPGA for Config • “Backdoor interface” for connection to host PC
Host PC with SLAAC-1V CONF Add an expansion interface 190 pin MICTOR LE 64-bit PCI slot 64-bit PCI slot 64-bit PCI slot PCI MC0 512 MB DIMM Raw 512 MB DIMM MC1 512 MB DIMM 512 MB DIMM RE 190 pin MICTOR • Xilinx XC2V3000 FPGAs for LE and RE • 190-pin MICTOR connectors for general use
Host PC with SLAAC-1V CONF Finally, some I/O interfaces 190 pin MICTOR LE 64-bit PCI slot 64-bit PCI slot 64-bit PCI slot PCI MC0 512 MB DIMM Raw 512 MB DIMM PI MC1 512 MB DIMM Audio In/Out 512 MB DIMM 100 MHz ADC RE RS-232 Port Daughter-card Connector 190 pin MICTOR Keyboard Port LCD Connector • Xilinx XC2V3000 FPGA for controllers • Various integrated devices and connectors
Integrated I/O and Connectors • Audio frequency ADCs and DACs • 2 channels, up to 44.1 kHz, 16-bit samples, RCA jacks • High-speed analog to digital converter • Up to 100 MHz, 12 bit precision, SMB connector • Serial (RS-232) port w/ 16550 UART • 9-pin D-SUB connector • PS/2 keyboard port (controller in FPGA) • LCD connector • 4x40 character, text-only LCD display: Optrex DMC-40457 • Daughter-card connector • Planned: 100 Mbit Ethernet and USB 2.0 controllers • 50 signal pins, 66 MHz clock, 5V and 3.3V power
