miXo is a buzz machine (www.buzzmachines.com) - a plugin for the freely available jeskola buzz tracker. it allows using the pc keyboard as a mixer which comes in handy when doing live performances with buzz.
詞法分析器的實(shí)現(xiàn)，1） 輸入:字符串(待進(jìn)行詞法分析的源程序),輸出:由(種別碼,自身值)所組成的二元組序列。
2） 功能:
a. 濾空格
b. 識別保留字
c. 識別標(biāo)識符
d. 拼數(shù)
e. 拼復(fù)合單詞: 例如： >=、 <=、 :=
3） 檢查如下錯(cuò)誤：
a. 程序語言的字符集以外的非法字符
b. 單詞拼錯(cuò),如9A88,而對于將begin拼寫成begon的錯(cuò)誤,只須把begon當(dāng)成標(biāo)識符即可
This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.

Pathload is a tool for estimating the available bandwidth
of an end-to-end path from a host S (sender) to a host R (receiver).
The available bandwidth is the maximum IP-layer
throughput that a flow can get in the path from S to R,
without reducing the rate of the rest of the traffic in the path.
This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University.
The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.
