The field that Radu Hobincu's book addresses - the optimization of microelectronic computing architectures - is very topical considering the increase in the degree of integration and the requirements related to the decrease of the energy consumed per computing unit. In the field addressed by the author there are still critical problems due to the difficulty of overcoming the problems imposed, mainly by the "memory wall", but also due to software integration problems that limit the effective use of the silicon area. The solutions offered by the author start from the analysis of the development stage of the field, they are effective and original.
