General purpose flags (ACFs) are defined and encoded utilizing a hierarchical one-, two- or three-bit encoding. Each added bit provides a superset of the previous functionality. With condition combination, a sequential series of conditional branches based on complex conditions may be avoided and complex conditions can then be used for conditional execution. ACF generation and use can be specified by the programmer. By varying the number of flags affected, conditional operation parallelism can be widely varied, for example, from mono-processing to octal-p...
1. A single instruction multiple data stream (SIMD) machine with a controller (SP) and at least two processing elements (PEs), each PE in said SIMD machine comprising:an arithmetic unit which receives at least two operands from a register file; instruction control lines derived from a registered instruction that was received from the SP in a processor pipeline, the instruction control lines including conditional execution control lines to control conditional operation as specified in an instruction; the arithmetic unit producing a result and a latched ar...
