The FM24C256/C256L/C256LZ devices are 256 Kbits CMOS nonvolatile electrically erasable memory. These devices offer the designer different low voltage and low power options. They conform to all requirements in the Extended IIC 2-wire protocol. Furthermore, they are designed to minimize device pin COUNT and simplify PC board layout requirements.

這是大學(xué)操作系統(tǒng)進(jìn)程調(diào)度實(shí)驗(yàn)的其中一個算法。實(shí)驗(yàn)中應(yīng)該要注意的是關(guān)于C中指針的用法，因?yàn)橹羔樀挠梅ū容^靈活又非常容易出錯，一不小心應(yīng)用不嚴(yán)密就會出錯。如在實(shí)行按短作業(yè)優(yōu)先算法調(diào)度進(jìn)程的過程中，每一次輸入無論是周轉(zhuǎn)時間，運(yùn)行時間，還是響應(yīng)時間都要用指針返回arrivetime，否則就出錯。還有在插入和釋放結(jié)點(diǎn)時，用此中指針表示法會比用for循環(huán)語句簡明很多。再一個就是在選擇運(yùn)行時間最小的進(jìn)程時，察看當(dāng)前就緒隊(duì)列中的進(jìn)程數(shù)也是很關(guān)鍵的，其間所得的COUNT對于下面兩步都很重要。

cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide. the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972. here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation. you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont COUNT). to eliminate these too, would involve ieee hackery.

Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer COUNT dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.

This program sets up EVA Timer 1, EVA Timer 2, EVB Timer 3 and EVB Timer 4 to fire an interrupt on a period overflow. A COUNT is kept each time each interrupt passes through the interrupt service routine. EVA Timer 1 has the shortest period while EVB Timer4 has the longest period.
