A rewrite table (107) contains an item representing the executed state of the rewrite block.

A detection of the majority state of the write back bits and a conditional inversion of write back bits are employed to reduce the number of write back pulses.

If the prior redraw operation is being carried out on said pixel, the control unit commences the next redraw operation after the prior redraw operation ends.

A message unit adding/rewriting information storage part (13) stores the message unit adding/rewriting information.

The system also generates the rewriting suggestion when it is determined that the rewriting suggestion should be provided.

This rewrite is a rewrite of the past of humanity!

The rewrite operation is performed during a still image rewrite period including two video scan periods (T11).

A rewriting section (103) refers to the rewrite table (107) to detect an unexecuted block in the software, and rewrites the unexecuted block by means of a rewrite block stored in the rewrite block storage section (106) in order.

This rewrite is a rewrite of the past of humanity!

A rewrite block storage section (106) temporarily store therein a rewrite block sent from a transfer section (109).

If the prior redraw operation is not being carried out on the pixel whereon the determination unit determines that the redraw operation is to be carried out, the control unit commences the redraw operation.

Some of them include completion of the CSRSS rewrite and the first stages of a shell32 rewrite.

All processing units in the plurality share the write back buffer.

At some point in time after retirement of the locked instruction, the writeback unit may perform a writeback operation associated with the locked instruction.
