OS9-ACRTC emulation software

Description

OS9-ACRTC is a OS-9 software package which emulates the widely used HD63484 Advanced CRT Controller (ACRTC) video processor from Hitachi.

The OS9-ACRTC software package consists of a device driver and a C library which provide a one to one translation of the ACRTC command set. The majority of the ACRTC operations, except a few obscure hardware-dependent features, are fully emulated by the software with excellent performance.

With the popular HD63484 processor now fading out, this package can a plug and play replacement for many existing boards and applications. By using one of Snijder Micro Systems' IndustryPack graphic modules and the OS9-ACRTC software, users can easily upgrade from legacy VME boards based on the HD63484 chipset. Most applications will run with little or no modifications on the new platform, saving a considerable amount of development time and effort.

The OS9-ACRTC software is not only useful for migrating existing HD63484-based systems, but is also a very efficient, royalty free device driver on its own, suitable for general use. The user's manual is available upon request. Sample C code illustrating some of the OS9-ACRTC functions is available here.

Licensing and availability

OS9-ACRTC is available for both VGA and LCD controllers. Users only need to pay a one-time license fee for unlimited use with Snijder Micro Systems' IndustryPack graphic modules.
