Java webstart should work again... (of course, you still need
to accept running the app despite the self-signed signature).
As it turned out, recent versions of the JDK
didn't like the fact that our webserver defaults to https:
protocol for all content, while the .jnlp files still
referenced the JAR archive via plain http: URLs.
First prototype of Hades Android running (but not released
Added two new variants of the relay toggle flipflop,
both of which are supposed to actually work with relays.
The previous demo is still online, but one user reported
that the circuit has hazard-errors and can malfunction
depending on the switching speed of the relays.
First ready-to-run D*CORE webdemo:
Sieve of Eratosthenes.
This includes the microcode and a simple assembly program
that calculates a few prime numbers.
Several minor fixes:
correct broken links due to our webserver restructuring;
applets now include the help files for the waveform-viewer (styx);
add missing screenshots in the Femtojava (pipelined) demos;
update the MIPS R3000 demos.
First applets showing the new TinyMips simulation model,
a simple MIPS-I (R2000/R3000) compatible 32-bit microprocessor.
Together with the corresponding memory (with byte-enable signals),
a complete and typical 32-bit microcontroller system can be built
This also lets you demonstrate the typical embedded systems
software development with a crosscompiler.
Documentation still incomplete, though.
New simulation model of the 8251 UART (USART)
and several applet demos for it.
Back online; sorry for the downtime! Our servers were ok,
but the whole informatics department got disconnected from the internet
for almost tree days due to a damage glass-fibre.
Uploaded a revised version of the
Uploaded a first set of applet demos using the MIPS-3000 processor.
Several new cosimulation applets based on the PIC16F84 and
Added a set of 'Femtojava' processor architecture and cosimulation demos
(provided by Prof. Ferreira from UFRGS, Brazil).
Added the 'news' and 'links' pages to the website.
Several new state-machine demonstrations in the applet collection,
starting with a simple
Added the thumbnails visual-index
to the applet collection.
Switch-level simulation support in the simulation kernel via
This allows simulating relays and transmission-gate circuits.
Please check out the new interactive
relay demonstration applets.
Finally uploaded the redesigned and long-overdue new website.
applet-collection is now online!
