The real-time operating system specialist, Microware Systems (UK) Ltd of Fareham, Hampshire, has announced enhancements to its OS/9 operating system, which started life on the 8-bit Motorola 6800 microprocessor. Microware says that these enhancements will benefit systems designers. The company has developed a ROM-based debugger, ROMbug, which can be used to debug interrupt service routines. Support is provided for the 68332 32-bit microcontroller BCC evaluation system. The Random Block File (RBF) manager – a module supporting random access, block oriented mass storage devices, with the ability to handle any number of these system types simultaneously and maintain the logical and physical structure of a file – can now support variable sector sizes of any integral binary power ranging from 256 to 32,768, which increases disk input-output throughput. The RBF also supports write-through disk caching, again to help disk input-output.
