Design of typical subsystems: arithmetic and logic operations, data paths, control units, memories, etc. Intellectual property blocks (IP blocks). Efficiency, portability and scalability of the code. Design of a digital system of practical interest: specification, synthesis, simulation and implementation on a current device.



6- High-speed architectures

System speed: measurement parameters. High performance architectures. Low latency architectures. Timing and clock signals.



7- Optimization of resources

Reuse of logical resources. Control of the management of resources. Shared logical resources. "RESET" structures: impact on the optimization of the area.



8- Optimization of consumption

Power consumption in CMOS technology. Terms of consumption in CPLDs and FPGAs. Low consumption families. Techniques to reduce consumption in CPLDs and FPGAs.

The subject is taught through lectures (20 h), practicals (10 h) and seminars (5 h). In addition to classroom practicals, the course also includes laboratory practicals (15 h) and computer practicals (10 h). In the first half of the course, theory classes are present the fundamentals of the technology of programmable devices, from the first devices to their current state. The theory classes of the second half are on the VHDL language. With regard to the theoretical part of the course, there are exercises in the design of circuits and digital systems. Periodically a class is devoted to discussing the solutions proposed by the students. Learning is complemented with the design, programming and verification of digital systems of practical interest in the laboratory using computational tools to aid design and development cards. In addition, the eGela tool is used as a means of communicating with students and as a platform for disseminating material and teaching resources.

Además, se utilizará la herramienta Moodle como medio de comunicación con el alumno y como plataforma de difusión de material y recursos docentes.

En la evaluación de la asignatura de tipo continuo se valorará:



- Prácticas e informes: 30 %

- Exposición oral de trabajos: 10%

- Prueba escrita individual: 60% de la nota de la asignatura



La prueba escrita constará de problemas a resolver, cuestiones de teoría aplicadas a los problemas propuestos y preguntas relacionadas con las prácticas de laboratorio. La calificación final se obtendrá de la media ponderada de las calificaciones previas, pero es necesario sacar una nota mínima de 5 sobre 10 en la prueba final individual.

Además, la realización de las prácticas de laboratorio es obligatoria para aprobar la asignatura por el sistema de evaluación continua.

A lo largo del curso se irán dando orientaciones de mejora de los trabajos entregados para guiar al alumno en la mejora de posteriores entregas.



Los y las estudiantes que no quieran participar en la evaluación continua deberán solicitar por escrito al responsable de la asignatura la renuncia a la evaluación continua en un plazo de 9 semanas desde el inicio del cuatrimestre.



El sistema de evaluación final consistirá en una prueba escrita individual y un examen de prácticas



- Prueba escrita individual: 60% de la nota de la asignatura

- Examen de prácticas de laboratorio y exposición oral: 40% de la nota



La prueba escrita constará de problemas a resolver y cuestiones de teoría aplicadas a los problemas propuestos. La calificación final se obtendrá de la media ponderada de las calificaciones previas, pero es necesario sacar una nota mínima de 5 sobre 10 en la prueba escrita individual. El examen de prácticas de laboratorio se realizará después de haber aprobado el examen escrito e incluirá la redacción de informes y una exposición oral.



Dado que el peso de la prueba final es superior al 40% de la calificación de la asignatura, bastará con no presentarse a dicha prueba final para que la calificación final de la asignatura sea no presentado o no presentada.
