dc.descriptionThe article is devoted to the development of synthesis and optimization methods of compositional microprogram control units (CMCU) on FPGA (field-programmable logic arrays). Compositional microprogram control unit, particularly the structure of CMCU with code sharing, is effective tool for application of linear control algorithm. For optimization of a system-on-a-chip resources, applied in realization of the compositional microprogram control unit, the method of a structural reduction is used. A method for reducing the hardware amount in the circuit of CMCU with elementary chains oriented on FPGA technology is proposed. This method is based on the usage of three sources of codes classes of pseudoequivalent EOLC (elementary operational linear chains) and a multiplexer to choose one of these sources. Main steps of proposed method include: forming and optimal encoding of EOLC; definition of classes of pseudoequivalency; transforming of tne initial table of transitions and sharing it by two parts according to the classes; forming of control memory content; definition of functional expressions for the block of code transforming. Such an approach would reduce the number of LUT (look-up table)-elements in the addressing circuit of CMCU. Application of the specified method to the finite state machine of addressing CMCU, under its implementation with FPGA, leads to reduction of the number of LUT-elements in the circuit of the control unit. Moreover, modern FPGA contains macrocells of embedded memory blocks (EMB). Such blocks can be reconfigured towards changing of input’s and output’s number with saving of fixed square of EMB macrocell. This property allows to apply the combinational circuit for multiplexer of code source using the tristable outputs of EMB. Proposed method uses this property for reducing the number of used macrocells in the logic circuit of CMCU. Results of research of the developed structures, allowing defining their efficiency and an area of optimum application, are discussed. And the example of the application of proposed method is given.en_US
