After the work on the Suska ip core has been slowed down this years in the light of recent events, the core is roughly in a state as of February this year. Nevertheless the Suska-III-C core has been improved a little bit. In the download area there are all respective files. Interesting for the owners o a Suska-III-C boards might be the timing improved configuration files which provide a better stability of the boards.

works as of February 2011: the development of the Suska ip core continues steadily. Due to the availability of the different Suska hardware platforms Suska-III-C, Suska-III-B and Suska-III-T, the development of the microcontroller firmware and the digital modelling of the FPGAs results in parallel development.

Suska-III-B: We work on the completion of the firm- and configware of the Suska-III-B boards. While the configware (digital modelling) of the FPGA is at 100%, the completion of the firmware of the Atmel microcontroller which handles the system control, the PS/2 mouse- and keyboard transfer and the SD card management will last a while.

Suska-III-C: The Suska-III-C ip core, which is developed and maintenanced since years, is currently examined concerning incompatibilities and improved in this sense. Smaller bug fixes were done in the recent time (DMA sound, real time clock). There are some programs which do not work on Suska-III-C. We currently evaluate, if the 68K00 ip core could be responsible for this behaviour. The firmware of two microcontrollers (PS/2 and system control) is complete. The third controller which shall handle the sd card and the ability to upgrade the FPGA respective boot device via the sd card is in progress means is developed hand in hand to the work on the Suska-III-B firmware. Currently the is no publicly available sd card firmware for this controller.

Suska-III-T: the work on the ip core of the smallest but most performant Suska board is turning out to be most complex of all. Because the Suska-III-T hardware is developed completely as a 32 bit system, there is a need to have the 68030 microprocessor available. Therefore the work currently focuses on the development of the digital model of such a 68030 respective the 68K30 ip core which shall later provide a functional compatible model compared to the original CPU. The current status is as follows: the bus controller in conjunction with the internal data- and instruction caches, the cache controller and the memory management unit (MMU) which interferes with the mentioned functional modules is completed and in intensively testing. We assume, that the completion of the 68K30 will last a longer time up to now.

The Suska ip core version 2K10B is available for download now (20101229). What's ahead? This year we will provide new hardware and extensions over the existing ip core. Happy New Year to all; have fun. w.

We have released the Suska-III-C configware in it's version 2K10A. We have introduced several details, which resulted among others from feedback of users of the Suska-III-C boards. Generally spoken, the new configware version can be considered a maintenance release. Unfortunately we are very busy in the moment and can not provide both, software and hardware development. So we have decided to bring out more suffisticated changes in the version 2K10B if there are people supporting the project by writing software for example drivers for ethernet, audio or USB. Have a look at the release notes in the Configware directory.

enjoy WF.

Currently we work on several updates of the Suska-III-C IP core. We have improved the ACSI-SCSI bridge to get SCSI-II devices working. Furthermore there is an updated RP5C15 real time clock emulation; so we have now a working real time clock. There are also investigations to improve the audio DAC functionality and the DMA sound system. The IP core of Suska-III-B is nearly finished. More informations on Suska-III-B will be released in the near future.

The Suska IP Core in it's version 2K9B is out now. It features improved stability a bunch of improvements resulting from the feedback of the Suska-III-C boards and significant changes to prepare the core concerning Falcon functionality and upgrade capability. See the readme file for more information. You can download the stuff from www.experiment-s.de. WF

The Suska IP core for the Suska-III-C boards will be released in December in version 2K9B. It features excellent stability and fixes some bugs. Furthermore there are several significant sructural changes to meet better compatibility for enhancements concerning Falcon functionality. Shortly the Suska-III-B will be presented on experiment-s.

The Suska IP core is now in a rather stable condition. The feedback of testers using the Suska-III-C board gave us very useful information to improve several details. The Suska-III-C boards has been exhibited on the Eurocon 2009 in Vienna and the ABBUC annual general meeting in October 2009. Suska-III-C will feature in the future Falcon functionality. Therefore we work on the IP cores of the COMBEL, the VIDEL and the Falcon DMA. The working title of this effort is 'Core-F' which will first be released as a configuration file especially for the Suska-III-C boards. WF.

Suska-III-C can now handle PS/2 keyboards and mice. The Joystick 1 is useable via the auxiliary port of the PS/2 microcontroller.
