| Research Topics Calculator Demonstration of user interface programming in F-PC. A calculator front panel is displaced and you can use it to do numerical calculations. Fourier Transforms Continuous Fourier Transforms (CFT) implemented on RTX2000 chip. CFT algorithm allows parallel processing, and a 4 processor system is constructed to run at 10KHz sampling rate. GameBoyAdvance GameBoyAdvance (GBA) from Nintendo is a powerful computer with 32-bit ARM7 as its core. We hijack it and build a interactive FORTH computer by programming its flash memory card. ARM7-eForth is ported to this system. Its is converted to a Chinese eBook. Mandelbrot Plots Mendelbrot plots were generated under F-PC. We evaluated 16- and 32-bit integer implementations, and a floating point implementations using 8087 to do the computation. Electronic Organ An electronic organ was built using 4 8253 counter-timers generating 12 square waves with independently controlled frequencies. Many organ music, about 10 hours playing time, by J. S. Bach were coded and played on this organ. The source code were originally in F83 blocks. A large portion was converted to sequential text files for F-PC. Search Engines DC7 is a single chip prallel search engine, which contains 7 comparator pipelines, each is 70 bits long. It can search 7 70-bit patterns from a continuous stream of text data and report matches instantaneously at 50 MHz clock rate. . Sorting Radix Sort is the simplest sorting algorithm. It was entered into the Sorting Contest hosted by Forth Interest Group in 1989. Submarine Finder Analyzing the phase differences in the audio signals received by two properly positioned sonar receivers could determine the direction of the source of the audio waves. It is useful in hunting submarines. GO Game Joseiki is the opening games in GO, the popular board game in China and Japan. This project started to document the standard Joseiki steps so that students can see these games played out on computer to help them recognize these patterns and thus strengthen their playing. |
