AT40K05LV General Description
The AT40K/AT40KLV is a family of fully PCI-compliant, SRAM-based FPGAs with distributed 10 ns programmable synchronous/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 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 5V designs for AT40K and 3.3V designs for AT40KLV.
The AT40K/AT40KLV 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 provide seamless integration with industry standard tools such as Synplicity, ModelSim, Exemplar and Viewlogic.
The AT40K/AT40KLV can be used as a coprocessor for high-speed (DSP/processorbased) designs by implementing a variety of computation intensive, arithmetic functions. These 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.
