We then observe that those same design forces now are bearing down on the architects of contemporary general-purpose processors, who consequently are producing general-purpose processors whose architectural features are increasingly similar to those of systolic arrays. We then describe some economic and technological forces that are changing the landscape of architectural research. At base, they are the increasing complexity of technology and applications, the fragmenting of the general-purpose processor market, and the judicious use hardware configurability. We describe a 2D architectural taxonomy, identifying what, we believe, to be a Bsweet spot^for architectural research.

The BCAL system consists of a global controller that feeds power, bias voltage and trigger signals to 96 local controllers situated at the ends of the 48 BCAL modules, which drive 40 LEDs associated with the 40 light guides at the end of each module. The FCAL system consists also of a global controller, a local controller for each acrylic quadrant covering the face of the FCAL, and ten 4-LED pulser boards per local controller connected in a star configuration along the edges of the acrylic panes. The respective systems are currently being installed on the detectors and their tested performance is presented herein.
