چکیده
In ASIC construction, design changes can occur at all phases of the product development cycle. When changes occur late in the development cycle, say after datapath synthesis and verification, it can be very expensive not to maintain a significant portion of the pre-existing design. However, changes in this environment require accommodation of the limitations of the pre-existing data-path, which potentially restrict operand movement, operand storage, or control encoding.Required changes may be in the data-path structure, in the input data-flow specification or may simply be attempts to remove critical communications which are limiting the performance. A variety of problems arise from these consideration including optimal memory operand binding, optimal function unit and communication binding, and optimal data-path constrained scheduling. This thesis presents an automata model with which to systematically explore the mapping freedom between a data-flow graph and a pre-defined data path. This technique shows great potential for accommodating last minute design changes or

Against the Current: Farid al-Din ‘Attar’s Diverse Voices
Love and its transformative power have long been at the center of Islamic Sufism. For Sufi writers profane love, perceived as the love of worldly beloved, was the first step on the path toward the union with the divine. Farid al-Din ‘Attar (1145-1221) was one of the most significant authors to espouse and articulate profane love as a representation of both earthly and heavenly love. 'Attar’s us...
