[DSP-10] New $99.00 EZ-Kit Lite (Blackfin family)

Sat, 13 Dec 2003 05:37:44 -0000

Atmel's FPSLIC concept was using the FPGA as a DSP coprocessor for an AVR CPU.
The FPGA need only be configured for a few types of filtering operations so
programming could be limited to loading coefficients. A general-purpose MCU can
then perform all other operations. The ARM and MIPS 32-bit CPUs have development
tools available under a GNU license at no charge.
