i860-based Bus Boards
FT-200-PCI Processor
Board for PCI Bus
Based on Intel's i860
processors, the FT-200 processor boards are ideal for accelerating
digital signal processing (DSP), graphics, and imaging processing
applications.
The Intel i860 microprocessor
delivers supercomputer performance in a single VLSI component. The
64-bit design of the i860 balances integer, floating point, and
graphic performance, and its architecture makes it suitable for
many applications including engineering workstations, scientific
computing, 3-D graphics workstations, and multi-user systems.
FT-200-PCI
Features
Features common to all
Alacron i860-based boards include:
- Single or Dual i860s
- Up to 200 MFLOPS /
100 MIPS
- Up to 272 MB Addressable
Memory
- FastTrack connection
to I/O and processor daughter-cards
- Real-time OS
- MS-DOS, Windows, Unix
interfaces
- Available for: PCI
and VME computers
The FT-200s are single
or dual 50 MHz i860 XP-based board-level subsystems, available for
PCI and VME bus computers. The FT-200 implements a fully symmetric
multiprocessing model, sharing addressable memory equally between
i860s. The FT-200 has a 200 MB/sec system bus, and with two processors
operates at 200 MFLOPS / 100 MIPS. The FT-200 can execute a 1K complex
FFT in under 0.320 mSec using both i860's, and in 560 mSec using
a single processor. The FT-200's addressable memory is expandable
from 8 MB to 272 MB.
The FT-200 subsystem
provides two FastTrack expansion connectors. These connectors implement
Alacron's stackable daughter-card protocol, and together can support
a combination of up to six I/O, memory expansion and processor daughter-cards.
Alacron provides a complete
family of high-performance FastTrack daughter-cards to allow sufficient
speed and buffering for intensive I/O and display, and to support
a wide range of third-party solutions. FastTrack interfaces
include:
- High Performance Digital
(Camera) Interface
- Analog Framegrabber
- High Performance Digital
I/O Interface
- DT-Connect Interface
- SCSI Interface
- VISIONbus Interface
- Video Display Adapter
- VSB Interface
The FT-200 accommodates
one or two i860s in a shared-master architecture. Each FT-200 board
features up to 272 MB of local DRAM, an on-board real-time clock,
programmable LED, interrupt controller, bus arbiter, and two FastTrack
connectors.
| Control
Registers |
Each
i860 processor has its own set of control registers within the
FT-200 shared memory address space. These registers control
the real-time clock, i860 interrupts, processor-bus arbitration
and interprocessor communication. |
| Real-time
Clock (RTC) |
The
RTC can be used to measure processing times, to generate periodic
interrupts to the i860, or to function as a time of day clock
on the FT-200. |
| Interrupt
Control (IC) |
IC
registers control interrupts to and from each i860 processors.
Each i860 may be interrupted from 5 sources: the other i860,
either expansion connector, the RTC, or the host computer. Each
i860 can interrupt the host bus as well as the other i860 processor.
|
| System
Bus Arbitration |
The
FT-200's i860 processors share the system bus with other RAM
masters in the following priority: DRAM Refresh, FastTrack Connector
#1, i860 Processors. |
| Dual
Processor Arbitration |
Dual
i860 processor arbitration is supported using LOCK and KEEP
functions, allowing either processor to assert and retain control
of the bus for as long as required. This is especially useful
for long I/O transfers. |
| Cache
Coherency |
The
integrity of data simultaneously cached by both processors is
enforced by cache write-through and bus snooping. |
| Memory |
The
FT-200 can be configured with either 8 or 16 MB of DRAM on the
main board. Two DRAM expansion boards may be added with 8, 16,
24, 32, 64 and 128 MB each, providing a maximum memory configuration
of 272 MB. FT-200 memory achieves a peak access rate of 200
MB/sec for near (on page) accesses and 66.66 MB/sec for far
(off page) accesses. FT-200 for the PCI bus computer can be
configured from 2 to 256 MB. |
