  • Patent number: 6175247
    Abstract: A context switching logic cell with public and context private data sharing for use in a context switching system. A context switching logic cell includes a programmable logic unit using configuration bits for implementing programmable logic functions for each context, a context memory for storing and providing results of context dependent logic operations, and carry logic. The context memory includes private registers, public registers and an active register. Each private register corresponds to a context and is addressable only within the corresponding context while public registers are addressable within all contexts and the active register stores results of logic operations for the current context. A context switching logic cell may include a data memory that is accessible within all contexts. The context switching logic cells may be arranged into a context switching logic array for use in a context switching system by level 1 buses and carry bit lines.
