In Proceedings of the 10th International Workshop on Hardware/Software Codesign, CODES, Estes Park (Colorado) May 2002. Scratchpad Memory: A Design Alternative for Cache On-chip Memory in Embedded Systems. Our optimization achieved an optimal solution for all benchmark programs. Our optimization achieved a reduction of program memory space between 2.7% and 18.2%, and an overall improvement with respect to instruction cycles between 5.1% and 28.8%.

Our benchmark suite comprises programs from MiBench and DSPStone plus a microcontroller real-time kernel and drivers for microcontroller hardware devices.

We have formulated the problem as a form of Partitioned Boolean Quadratic Programming (PBQP).We implemented the optimization as part of a PIC Micro-chip backend and evaluated the approach for several optimization objectives. The optimal placement is controlled by a variety of different objectives, such as runtime, low power, small code size or a combination of these parameters. Given a program in which variables have been assigned to data banks, we present a novel optimization technique that minimizes the overhead of bank switching through cost-effective placement of bank selection instructions. Bank switching is a technique that increases the code and data memory in microcontrollers without extending the address buses.
