IPC: G06F15/16
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a parallel operation processing units which can speedily and flexibly solve synchronization wait when plural tasks occur. SOLUTION: A processor element PE 12 specifies a pipe counter for PEs 13 to 15 calls out plural tasks and has a synchronization wait instruction performing synchronization wait as the necessity arises. An arbiter 156 increases a count value of a corresponding pipe counter when a task calling occurs and decreases the count value when the task is completed. The processor element PE 12 compares the count value included in the synchronization wait instruction with the count value of the pipe counter corresponding to the arbiter 156 when the synchronization wait instruction is executed, releases the synchronization wait when the values coincide with each other and performs the synchronization wait when they do not.

Filed: 1986-05-09
Abstract: PURPOSE:To suppress the possibility of the zero-cross of a focus error signal, by impressing a bias signal on the focus error signal, at a timing when the output level of an information signal exceeds a prescribed level. CONSTITUTION:When a signal RF exceeds a prescribed level (VR), a signal SRF outputted from an RF signal comparator 6 rises, and both two input signals of a NAND gate circuit 9 go to 'H' levels, and the output signal of the NAND gate 9 is inverted to an 'L' level. And a switch device SW is opened, and thereby, a bias voltage (offset voltage) decided by a variable resistance R2 is impressed on the input terminal of an operational amplifier circuit 5, and the potential of a signal FE is raised high by a share corresponding to the offset voltage. In such a way, the zero-cross of the signal FE can be prevented by a noise component generated by the time of the leading edge point of the S-curve of the signal FE.
