Description

 The AT40KAL is a family of fully PCI-compliant, SRAM-based FPGAs with distributed 10 ns programmable synchron-ous/asynchronous, dual-port/single-port SRAM, 8 global clocks, Cache Logic ability (partially or fully reconfigurable without loss of data), automatic component generators, and range of AT40K40AL in size from 5,000 to 50,000 usable gates. I/O counts range from 128 to 384 in industry standard packages ranging from 84-pin PLCC to 352-ball Square BGA, and support 3.3V designs.

The AT40KAL is designed to quickly implement high-performance, large gate count designs through the use of synthesis and schematic-based tools used on a PC or Sun platform. Atmel's design tools of AT40K40AL provide seamless integration with industry standard tools such as Synplicity, ModelSim, Exemplar and Viewlogic. See the "IDS Datasheet" available on the Atmel web site (http://www.atmel.com/atmel/acrobat/doc1421.pdf) for a list of other supported tools.

The AT40KAL can be used as a coprocessor for high-speed (DSP/processor-based) designs by implementing a variety of computation intensive, arithmetic functions. AT40K40AL include adaptive finite impulse response (FIR) filters, fast Fourier transforms (FFT), convolvers, interpolators and discrete-cosine transforms (DCT) that are required for video compression and decompression, encryption, convolution and other multimedia applications.
