This unit introduces the main concepts and tools used for advanced digital system design. A technology review of digital logic families is given as well as an explaination of memory functions, memory types, and the design of large memory arrays. An introduction to FPGA and CPLB programmable logic devices is given. Digital design and analysis methods, top-down design, algorithmic state machines (ASM), synthesis of ASM, sequencing and control and CPU design are also covered. An introduction to VHDL, and simulation and testing of digital systems is included.
