fpgatools is a toolchain to program field-programmable gate arrays (FPGA). The only supported chip at this time is the xc6slx9, a cheap but powerful 45nm-generation chip with about 2400 LUTs, block ram and multiply-accumulate devices.

This is the GNU Go compiler for the x86_64-linux-gnux32 architecture, which compiles Go on platforms supported by the gcc compiler. It uses the gcc backend to generate optimized code.

This is the GNU D compiler for the arm-linux-gnueabi architecture, which compiles D on platforms supported by gcc. It uses the gcc backend to generate optimised code.

This is the GNU D compiler for the hppa-linux-gnu architecture, which compiles D on platforms supported by gcc. It uses the gcc backend to generate optimised code.

This is C library which support talking with FSP server using FSP v2 protocol and provides posix-like file manipulation interface.

Funtools, is a "minimal buy-in" FITS library and utility package developed at the High Energy Astrophysics Division of SAO. The Funtools library provides simplified access to a wide array of file types: standard astronomical FITS images and binary tables, raw arrays and binary event lists, and even tables of ASCII column data. A sophisticated region filtering library (compatible with ds9) filters images and tables using boolean operations between geometric shapes, support world coordinates, etc. Funtools also supports advanced capabilities such as optimized data searching using index files.
