OPERATING SYSTEM
The Embedded System Platform is designed for use with a Linux
based operating system. Linux offers a multitasking operating
system, capable of real-time operation, while providing the
ability to read and write several file system types including
DOS and UNIX compatible file storage. Application program
development is accelerated by the availability of operating
system functions, which manage network and disk operations.
Additionally, the network capabilities of Linux provide the
ability to remotely access and administer operations and data
on the Embedded System Platform.
Microprocessor
The ESP-1 utilises the MCF5407 Motorola ColdFire embedded
processor. The processor connects to a 32-bit, 40 MHz system
bus, while internal clock multiplying results in a 162 MHz
internal processor frequency. Motorola rates the ColdFire
at 257 million instructions per second, in system performance
will most likely be lower, however the processor includes
8 KB program cache and 4 KB of user accessible static RAM
internally to optimize real world performance. An additional
512 K bytes of static RAM are accessible by the processor
externally, allowing the operating system or a process to
run entirely in fast static memory.
FPGA
The Embedded System Platform provides 74 programmable
I/O pins connected to a Xilinx Virtex field programmable gate
array, providing the ability to implement complex logic or
bus functions, while allowing dynamic logic changes by reloading
the FPGA configuration. The Virtex FPGA offers up to 100 Kb
of internal static memory with 5,292 dynamically programmable
logic cells, available for creating logic functions, registers,
and memory arrays.
The FPGA connects directly to the single board computer’s
system bus. This allows fast data and status information transfers
between the FPGA, CPU, and on board PCI bus, enabling the
unit to act as a bridge between dissimilar systems
to SCSI or other storage media.
PCI Controller
The Embedded System Platform includes a PLX 9054 PCI
bus master. The 9054 supports a 32-bit, 33 MHz PCI bus, running
at 3.3 or 5 volt logic levels. The configuration of the PCI
bus master allows 3 additional PCI devices to be added to
the single board computer’s PCI bus. The PCI bus is
designed to meet the PC/104-Plus "PCI Only" specification,
enabling the addition of commercially available PC/104 Plus
PCI Only expansion boards.
SCSI Controller
The QLogic FAS368M SCSI controller allows the single
board computer to utilize SCSI hard disk drives, tape drives,
and CD-ROM devices. The onboard SCSI controller supports SCSI
wide devices. Compliance with ANSI SCSI, SCSI-2, and SCSI-3
standards provides data transfer rates ranging from 7 MB per
second in Asynchronous mode up to 40 MB per second in Ultra
Fast SCSI mode.
Ethernet Controller
On board Ethernet connectivity is provided by an Intel 82558
10/100 Mbps Ethernet controller. This controller supports
both the 10 Mbps and 100 Mbps Ethernet standards with support
for half and full duplex operation.
SDRAM
The Embedded System Platform supports two PC-100 SDRAM
DIMM modules. One DIMM bank dedicated to the processor, the
other bank dedicated to the Virtex FPGA. The processor dedicated
SDRAM bank provides up to 256 MB of memory for the ColdFire
processor’s operating system and programs. The Virtex
FPGA dedicated DIMM bank supports SDRAM module capacities
up to 1GB, providing plentiful buffering of data and translation
information.
SRAM
To promote fast program execution and reduced interrupt latency,
the single board computer contains two levels of SRAM available
to the Motorola ColdFire processor. The first level consists
of an internal processor cache of 8 KB cache dedicated to
program caching. The remaining 4 KB is available for general
use by the processor. The second level of SRAM consists of
a 128K by 32-bit flow-through SRAM available for general use
in storing commonly accessed program code and data.
FLASH
Nonvolatile memory is provided using Intel StrataFlash memory,
with 8 MB capacity expandable to 32 MB. The StrataFlash memory
provides reliable long-term memory storage of program and
firmware information, with additional automated block erase
and block write protect features.
