Subject specific learning outcomes and competences
The student should be able to describe and simulate complex digital systems using VHLD language constructs including both behavioural and structural description. This course is recommended as a co-requisite for INC and INP.
To give the students the knowledge of syntax and semantics of hardware description language VHDL, its use for modelling, simulation, and synthesis of complex digital systems, as well as the skills in VHDL programming techniques and the use of professional design tools.
Why is the course taught
The VHDL Seminar supports INC and INP courses and is recommended to deepen the knowledge of VHDL language and issues connected with advanced hardware design. Students will receive a more detailed knowledge of VHDL not only theoretically but also practically as there are not only practical demonstrations but also a project on FITkit, development board equipped with programmable gate array XILINX. Mastering the hardware description language is a key element in the successful and efficient design of FPGA-based systems having a dominant position especially in the field of high-performance computing (network operations acceleration, acceleration of digital signal and video processing, acceleration of bioinformatic tasks, cryptographic applications, etc.), where the acceleration platforms based on FPGAs can achieve significant speedup gain at minimum power levels compared to the conventional parallelization techniques based on CPUs and GPUs. Knowledge of hardware description techniques enables students to actively engage in a number of research projects in the area of network data and security processing.
