FastFax is a small, lightweight fax and e-mail device capable of interfacing to cellular telephones. At the heart of the design is a reduced instruction set computing (RISC)-based processor which provides the speed, low power consumption and low cost required by the portable market. It is operated through on-screen menus allied to a limited number of buttons whose functions change to present options, in a manner similar to an automatic teller machine. This makes it extremely easy to use for non-computer literate professionals and allows simple multi-lingual support.
The paper handling and printing functions (rollers, stepper motors, printer heads, gearing, etc) have been replaced with a liquid crystal display screen for viewing and a printer port for producing hard copies. Without the document feed mechanism, users simply drag the unit across the page to scan the image, which is then stored before being sent. To achieve sufficient scan quality, fast processing is needed and the ARM7100 RISC-based core provides the necessary speed. With an application specific integrated circuit (ASIC) to provide support logic, this allowed very rapid development. Personal Computing Memory Card International Association (PCMCIA) slots are used as the most versatile way to interface to global system mobile (GSM) phones and public switched telephone network (PSTN) modems. The power supply was also designed so a single set of batteries provides 30 min of continuous scanning or 10 h of document viewing, and up to 30 d image storage in low power mode.
Local area networks (LAN) using asynchronous transfer mode (ATM) provide the speed and bandwidth needed for high quality, simultaneous voice, video and data transmission. Based around a single-chip controller, the VIRATAlink Network Interface Card (NIC) provides simple, low cost and high performance connection of desktop personal computers (PC) to ATM25 networks. Drivers for Windows are included and, with a network switch such as VIRATAswitch, it can be used to build high performance LANs running standard TCP/IP (the protocols used for Internet access). VIRATAlink also allows PCs to connect to new digital subscriber line (DSL) modems, which offer high data rate services over existing lines.
VIRATAlink uses the Hydrogen chip, a custom IC with an ARM7 core running at 32 MHz. It has PCI bus interface logic, an ATM25 analogue physical layer interface, ATM cell buffers, segmentation and re-assembly (SAR) logic and all other functions required to connect to an ATM25 network. It is supported by 1 Mbyte of external direct random access memory (DRAM) and an Ethernet media access controller (MAC) chip. The ARM core runs the ATMOS real time operating system kernel, which provides a full suite of ATM protocols and performs all functions for connecting to an ATM network. Signalling for the virtual circuits and LAN emulation are also included. VIRATAlink can also function as a standard Ethernet NIC. Device drivers for Windows 3.1x, 95 and NT support all standard network protocols, enabling new classes of multimedia applications to run on PCs across the LAN such as computer telephony integration (CTI).
