The article provides an overview of the main directions of the development of architectures of content addressable memory and associative processors. The main problems that are facing the developers of these devices are identified. The description of the content addressable memory of keys in the matching processor, which is the main computation process control device in the parallel dataflow computing system (PDCS) “Buran”, is given. Existing methods to increase the speed and reduce power consumption for various types of content addressable memory (CAM, TCAM, etc.) are considered. Various TCAM architectures implemented on the nonvolatile memory technology, as well as associative processors are described.

ABC is a tool that solves the logic optimization and technology mapping tasks in the digital circuits design flow. It is suitable for both custom and FPGA design flows. This tool is a technology independent solution and, accordingly, does not take the architectural features of the target FPGA into account. Although considering these features can significantly decrease the occupied area, in terms of programmable logic blocks and interconnections. This article presents modifications of the logic synthesis algorithms used in the ABC tool. Applying these modifications allows to obtain a more appropriate description of the circuit for performing logic architecture-oriented resynthesis.

IP-core is a block with a complex function that can be re-used in integrated circuits design. There are two types of FPGA IP-cores: hard IP-core and soft IP-core. Hard IP-cores have an exact location and pre-routed interconnects while soft IP-cores can be synthesized from logic elements and should be placed and routed. To use IP-cores in automated design flow of integrated circuits on FPGA it is necessary to develop IP-cores libraries that allow identifying blocks on every stage of *** article shows IP-core libraries types and forms used as a part of design flow developed by IPPM ras for Russian FPGA. It describes challenges of libraries for logical synthesis development and automatic mapping on an existing basis. The paper presents libraries needed by CAD on every stage of physical design for clustering, placement and routing. Also, it considers soft and hard IP-cores libraries distinct features and methods of their formation taking into account the FPGA architecture.
