In addition to the CPU, memory, and I/O building blocks, other logic
circuits may also be required. Such logic circuits are frequently
referred to as glue logic because they are used to connect the
various building blocks together. The most difficult and important task
the hardware designer faces is the proper selection and specification of
this "glue logic." Devices such as registers, buffers, drivers and
decoders are frequently used to adapt the control signals provided by
the CPU to those of the other devices. While TTL gate level logic is
still in use for this purpose, the programmable logic device (PLD)
has become an important device in connecting the building blocks.
Contemporary microcontroller designers need to acquire the following
skills:
- Interpretation of manufacturers specifications
- Detailed, worst case timing analysis and design
- Worst case signal loading analysis
- Design of appropriate signal and level conversion circuits
- Component evaluation and selection
- Programmable logic device selection and design
