the attached utility is a work I ve submitted to the university
It shows what a jpeg compression is all about.
the function implements the DCT transform, using a matrix operator.
Note that matlab has a function for the DCT and iDCT transforms
that might be more efficient.
Back in 2002, the 6502 disappeared out of all catalogues.
Wanted to know, if it s possible to build a binary compatible CPU with the things I had in the drawer:
74LS parts, 27C512 EPROMs and a fast static RAM from an old 80386 motherboard.
Now here the results.
Note, that the Bus timing is different from the 6502.
Without this, the debugger spontaneously fails!
1 - Install mdk315b
2 - Replace the files:
\Keil\ARM\BIN\ARM.DLL with one from mdk305a\Keil\ARM\BIN\ARM.DLL
\Keil\ARM\BIN31\ARM.DLL with one from mdk305a\Keil\ARM\BIN30\ARM.DLL
\Keil\UV3\UV3.DLL with one from mdk305a\Keil\UV3\UV3.DLL (*)
3 - Use KeyGen (Ver3p4 works)
Select ARM, With computer ID code , External CID code
and RealView MDK (or RealView RL)
Note: Must replace DLLs before entry of serial
(*) - May not be necessary (???)
Fast settling-time added to the already conflicting requirements of narrow channel spacing and
low phase noise lead to Fractional4 divider techniques for PLL synthesizers. We analyze discrete "beat-Note spurious levels from arbitrary modulus divide sequences including those from classic accumulator methods.
CRM源碼This file describes some issues that should be implemented in future and how it should be implemented.
Note: it should be implemented exactly how it described below, because another parts of system can rely on it.

Here is a geometric problem. You have an angle and some squares in the first quadrant of the plane rectangular coordinates. The vertex of the angle is fixed on the origin O of the coordinates, and both of its radial lines are specified by the input. The sizes of the squares are also specified by the input, and the squares can shift vertically and horizontally. Now your job is to use the squares and the radial lines of the angle to enclose the maximum area, which excludes the area of the squares (see Figure 1). You should Note that the edges of the squares must be parallel to the axes.
This package provides a complete http client library. It currently implements most of the relevant parts of the HTTP/1.0 and HTTP/1.1 protocols, including the request methods HEAD, GET, POST and PUT, and automatic handling of authorization, redirection requests, and cookies. Furthermore the included Codecs class contains coders and decoders for the base64, quoted-printable, URL-encoding, chunked and the multipart/form-data encodings. The whole thing is free, and licenced under the GNU Lesser General Public License (LGPL) (Note that this is not the same as the GPL).
simulates coin tossing. Let the program toss a coin each time the user chooses the “Toss Coin” menu option. Count the number of times each side of the coin appears. Display the results. The program should call a separate method flip that takes no arguments and returns false for tails and true for heads. [ Note: If the program realistically simulates coin tossing, each side of the coin should appear approximately half the time.]
