Abstract
 A software TurboGen has been worked out. It is defined as a subsystem of CAD for synthesis of VHDL specifications of the IP-cores of the convolution turbo codes encoder/decoder. A new structure of the turbo code computing system is highly fast acting for account of a pipelined me-thod in the designing along with an effective application of the core memory banks has been sug-gested. A particular emphasis is placed on the hardware support of a maximum a posteriori proba-bility algorithm (MAP) of the turbo coding device. The analyses of the logical synthesis results fur-thered to define and estimate the hardware expenditure, required for VLSI realization of the complex functional units of the convolution turbo codes encoder/decoder, and confirm the rationality of VLSI computing resources application.
