Overview Integrated Silicon Systems is a DSP intellectual property company specializing in synthesizable DSP products. ISS has an acknowledged worldwide competence in VLSI architectures for DSP and supplies highly optimized DSP circuit functions for ASIC, FPGA and CPLD implementations. The key advantages of using ISS products are: Highly efficient silicon implementations after synthesis Dramatically reduced design times for rapid prototyping and fast time-to-market Very high performance - orders of magnitude greater than programmable DSP cores Characterized for the worlds principal fabrication processes ISS's main products are: DSP system-level cores - A range of parameterized system level blocks (JPEG, ADPCM) for efficient ASIC, FPGA and CPLD implementation. DSP function-level cores - An extensive range of highly parameterized DSP function level blocks for efficient ASIC, FPGA and CPLD implementation. DSP ASIC library - A comprehensive library of over 170 parameterized, synthesizable DSP building blocks written in VHDL and are available in a number of fixed and floating point formats. All blocks are fully parameterized, allowing the ultimate in design flexibility and design reuse. ISS's range of functions is optimized for Xilinx FPGAs, giving Xilinx customers a unique advantage in the design of complex FPGA-based systems. AllianceCORE Products to view the  PDF files below.
