Abstract
System and method for the management of bit plane resources are presented. Because of the scarcity of processing element (PE) memory in a SIMD architecture, it is important to ensure that it is used with optimal efficiency. The Invention discloses methods for managing PE memory at runtime such that nearly 100% utilization is achieved. The method employed allows memory to be allocated and deallocated in single bit plane increments. Runtime allocation and deallocation occurs continuously such that it is impossible to guarantee availability of contiguous blocks of PE memory. The method employed by the invention allows scattered bit planes to be used without the necessity of expending execution time to perform “garbage collection”.
