 Introduction
- todo
+ fpgatools is a toolchain to program flexible programmable gate arrays
+ (FPGAs). The only supported chip at this time is the xc6slx9, a cheap
+ (ca. 10 USD) but powerful 45nm-generation chip with about 2400 LUTs,
+ block ram and multiply-accumulate devices.
+ The principles of fpgatools are:
+
+ *) reach the maximum physical performance of the chip
+ *) fast development cycles
+ *) independent toolchain that only depends on other free software
+ *) lightweight C implementation without GUI
+ *) supported platform: Linux
+ *) license: public domain
