The paper presents a new two-step approach to FSM synthesis for PAL-based CPLDs that strives to find an optimum fit of an FSM to the structure of the CPLD. The first step, the original state assignment method, includes techniques of two-level minimization and aims at area minimization. The second step, PAL-oriented multi-level optimization, is a search for(More)
In the paper, the state assignment methods of the finite state machines for PAL-based structures are presented. A main feature of the PAL-cell is a limited number of product terms (k-AND-gates) that are connected to a single sum (OR-gate). Function, which is the sum of p-implicants, when p/spl ne/k, does not take full advantage of the cell. When p>k,(More)
The logic synthesis of ultra-high-speed FSMs is presented. The state assignment is based on a well-known method that uses output vectors. This technique is adjusted to include elements of two-level minimization and takes into account the limited number of terms contained in the programmable-AND/fixed-OR logic cell. The state assignment is based on a special(More)
The paper presents performance analysis of a permanent magnet synchronous motor (PMSM) drive with torque and speed control. The PMSM motor requires sinusoidal stator currents to produce constant torque. The paper presents constituents for the mathematical analysis of the motor operation within the dq-axis model. The mathematical model serves as inspiration(More)
The paper presents different aspects of driving the permanent magnet synchronous motor (PMSM). The excitation in the PMSM motor is provided owing to permanent magnet instead of the field windings. Special construction causes that the PMSM motor has sinusoidal back EMF. The motor requires sinusoidal stator currents to produce constant torque. The paper(More)
