<P>PROBLEM TO BE SOLVED: To provide an improved very long instruction word processor with sequence control. <P>SOLUTION: During each cycle, this processor generates control signals to functional units based on the values in fields of an instruction. Each instruction may include an iteration count specifying the number of cycles for which the control signals should be generated based on that instruction. The instruction set further includes flow control instructions enabling repetitive execution of a single instruction, repetitive execution of a block comprising a plurality of instructions or branching within a program. Such a processor can be used in connection with a disk controller for a hard drive of a computer. The flexible sequencing allows a hard-drive controller to be readily reprogrammed for use in connection with different types of media or to be dynamically reprogrammed upon detection of a disk read error to increase the ability of the disk controller to recover data from a disk. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
