In this paper, an efficient methodology to retargeting and reuse of embedded mixed-signal blocks is presented. Parametrized layout templates, accurate behavioral modeling of mixed-signal blocks, and appropriate mechanisms for tuning sized circuits to new sets of specs are its key components.

This paper presents the complete design methodology of a very low-voltage ∆Σ third-order modulator from highlevel specifications down to layout. Behavioral models taking into account cell non-idealities are developed and used to map performance specifications to lower levels. Emphasis has been made on eventual design reuse through design plans and layout templates in a layout-oriented circuit d...

We study a supply chain with one supplier and many retailers that face exogenous endcustomer demands. The supplier and the retailers all try to minimize their own inventory-related costs. In contrast to the retailers’ newsvendor type ordering behavior (under which retailers may place orders freely in every period), we propose two scheduled ordering policies: Scheduled Balanced Ordering Policy (...

This paper presents the design of forthcoming wizard-of-Oz (WOZ) studies in the context of the EU-funded Metafora project that is developing a Computer-Supported Collaborative Learning (CSCL) system to scaffold 12 to 16-year-old students in learning to learn together (L2L2). In the Metafora system, students undertake lengthy collaborative challenges interacting in 3 different spaces: a planning...

Embedded systems are becoming increasingly important, appearing in every aspect of daily life. The cost of these systems is strongly influenced by the cost of the processor chip. The chip cost, in turn, is dominated by the die size. By compressing embedded software the space devoted to instruction memory can be reduced, lowering costs. Alternatively, more fully-featured software can be provided...
