A new Sparc-based co-processor system for AT-bus machines has been introduced by Definicon Systems (UK) Ltd of Battersea in South London. Using the 33MHz version of the Sun Microsystems Sparc RISC processor fabricated by Cypress Semiconductor, Definicon’s SP-ARC1 system combines the CPU with a floating point unit from Texas Instruments – the TI 8847 – and includes up to 8Mb of fast memory. It can be added to any 80286 or 80386-based box according to Definicon, enabling peripherals such as graphics cards, serial and parallel ports and optical disks to be accessed by the SP-ARC1 via the AT system bus, using the host CPU as an input-output controller. An optional SCSI port for direct data transfer is also available to avoid contention for host system resources. Definicon also produces Motorola 68030 and Transputer-based co-processor boards for MS-DOS boxes. No prices were given.
