Description
The past two decades have provided a wealth of experience in highly integrated
front-end electronics for high energy physics. The SLHC and ILC, however,
pose formidable challenges, not so much to technology, but to optimum utiliza-
tion of existing technology. The increased radiation load at the SLHC drives
detectors to higher segmentation, which exacerbates the problems of reducing
power and material. Vertex and tracking detectors at the ILC are driven by
position resolution and material, also linked to power dissipation. Power con-
straints also limit the readout rate, which affects the choice of trigger architec-
tures. One path to more efficient trigger systems is the use of hardware trigger
processors, which will become more powerful as the technology of FPGAs and
other digital hardware progresses. Following a review of current systems, I will
discuss various paths to attack these challenges.
