Multiple-process behavioral synthesis for mixed hardware-software systems

Finding optimal hardware/software partitions

“…the semantics of a node. There have been works on low granularity, where a node represents a single instruction or a short sequence of instructions [6,8,40,21], middle granularity, where a node represents a basic block [22,27,38], and high granularity, where a node represents a function or procedure [18,36,48,2], as well as flexible granularity, where a node can represent any of the above [20,47].…”

“…an assignment of values to the variables. 2 The internal nodes of the search tree correspond to partial solutions, i.e. assignment of values to some of the variables.…”

The design of mixed hardware/software systems

“…Co-design may also include integrated synthesis of hardware and software components, which we refer to as hardware/software cosynthesis [6] [7] [8] [9] [10]. Automated hardware/software co-synthesis may allow the designer to explore more of the design space by dynamically reconfiguring the hardware and software to find the best overall organization as the design evolves.…”

Partitioning framework for less restricted partitioning problems

“…The solution space for SOC design generally consists of a single processor core and a good deal of hardware implementation possibilities for each function block [6]- [17]. Therefore, a significant part of the component selection sub-problem is devoted to find out the optimal implementation of each hardware function block under design constraints such as execution speed, cost, and power consumption.…”

“…Since our taxonomy does not distinguish the detailed target architecture, we summarize the range of solution space as follows: (1) fixed architecture [4], [14]- [17] and (2) synthesizable architecture. Architecture synthesis consists of the following three sub-problems: (1) component selection [6]- [13], [21]- [24], (2) interface synthesis [21]- [24], (3) memory structure synthesis [28].…”
