    Abstract: Architectures and circuits are described for various implementations of a memory-centric computing system for DSP and other compute-intensive applications. A shared, reconfigurable memory system is accessible to both a host processor or controller and to one or more execution units such as a DSP execution unit. By swapping memory space between the processor and the execution unit so as to support continuous execution and I/O, improved performance is achieved while cost is reduced. The shared memory system includes multiple reconfigurable memory segments to allow allocation of various amounts of memory to respective execution units or I/O or DMA channels as needed to optimize performance. A "virtual two-port" solution is also described for using single-port memory in the shared configuration with multiple address sources.
