The PCF8578 is a low power CMOS1 LCD row and column driver, designed to drive dotmatrix graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has40 outputs, of which 24 are programmable and configurable for the following ratios ofrows/columns: 32¤8, 24¤16, 16¤24 or 8¤32. The ...
The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...

GameForge is a graphical tool used to aid in the design and creation of video games. It attempts to bring game development down to a level that any computer savvy user can understand, without requiring masterful programming ability. A user w ...
The Staged Event-Driven Architecture (SEDA) is a new design for building scalable Internet services. SEDA has three major goals:
To support massive concurrency, on the order of tens of thousands of clients per node
To exhibit robust performance under wide variations in load and,
To simplify the ...
The goal of this library is to make ODBC recordsets look just like an STL container. As a user, you can move through our containers using standard STL iterators and if you insert(), erase() or replace() records in our containers changes can be automatically committed to the database for you. The lib ...

* The internal form of a hash table.

* The table is an array indexed by the hash of the key collisions
* are resolved by hanging a linked list of hash entries off each
* element of the array. Although this is a really simple design it
* isn t too bad given that pools have a low allocation ...
Inside the C++ Object Model
Inside the C++ Object Model focuses on the underlying mechanisms that support object-oriented programming within C++: constructor semantics, temporary generation, support for encapsulation, inheritance, and "the virtuals"-virtual functions and virtual inheritance. This bo ...
