Specialix Ltd has introduced a new generation of input-output subsystems using the Inmos Transputer. The new system, called RIO, should take Specialix into new markets, by enabling a maximum of 512 users to be connected to an Intel 80386 or 80486 host system running Unix. Bandwidth is said to be increased tenfold over the Byfleet-Surrey-based firm’s current SI-Series products, which are Intel-based, and typically serve between eight and 16 users. For RIO, Specialix uses 25MHz T400 Transputers, and replaces traditional ageing universal asynchronous receiver-transmitter chips with the custom CD1400 communications processor from Cirrus Logic. A Transputer is used in the host input-output controller, and also in each remote eight-port terminal adaptor with the CD1400. Each adaptor can support three further remote terminal adaptors in addition to terminals, giving a maximum configuration of 128 terminals per card. Specialix marketing director Ian Cummins said that the Transputer was chosen because it has four very fast serial lines – it’s not just the power, it can carry on serial input-output without affecting its own processing. Cummins said that the boards also included minicomputer-style dynamic reconfiguration software to help users cope with many terminals. The 32-user version is UKP3,000 or so, a 128-port version UKP9,000.
