    One-hot state machine design for FPGAs by Steve Golson Abstract: One-hot state machines use one flop per state. They are particularly suited to today’s register-rich FPGA architectures. This paper will discuss the advantages of one-hot state machines including ease of design, simple timing analysis, and high clock rates. An SBus master/slave interface will be used…

    A solar eclipse occurs when the moon comes between the earth and the sun, and the moon casts its shadow on the earth. During totality the sun’s corona becomes visible as a white halo around the black disk of the sun. The sky darkens, but the entire horizon is lit with sunset colors. In this…

    A lunar eclipse occurs when the moon enters the earth’s shadow. The Greek philosopher Aristotle observed that during a lunar eclipse the shape of the shadow seen on the moon is always round. The only shape that always casts a round shadow is a sphere; thus Aristotle concluded that the earth was spherical some eighteen…

    A 2K byte fully-associative cache memory with on-chip DRAM control by Scott Griffith and Steve Golson Abstract: A 2Kbyte cache memory with on-chip DRAM control has been built. The fully-associative write-back write-allocate cache is organized as 128 lines by 16 bytes. The part directly connects to and controls an array of 1 Mb DRAMs forming…

    Iridescence in clouds is caused by diffraction of sunlight off cloud droplets of very uniform size. Such uniformity is characteristic of “young” clouds; older clouds have a wider distribution of sizes due to the coalescing of droplets. In cirrus clouds like these the diffracting agent may be tiny ice crystals or frozen droplets. Rainbows are…

    This photograph was made by aiming the camera at Polaris, the pole star. The earth’s axis of rotation points toward one spot in space, and in a time exposure photograph all the stars seem to revolve around that one point. Notice that Polaris is not exactly centered on the celestial pole but makes a tiny…
