Title: Detecting method for waiting state of microprocessor and personal computer
Inventor: TAKEDA KOJI
IPC: G06F12/08
Filed: 1990-06-28
Abstract: PURPOSE:To reduce the power consumption of an equipment by providing a cache memory of small capacity between a microprocessor and a main memory and deciding that the microprocessor is kept in a waiting state when the cache memory shows a hit state. CONSTITUTION:A cache memory 3 of small capacity is provided between a microprocessor 1 and a main memory 2, and it is decided that the microprocessor 1 is kept in a waiting state when the memory 3 shows a hit state. In other words, a program is looped in the waiting state and this loop is usually set at >=64 bytes. Thus all instructions included in the loop are erroneously stored in the memory 3 if the loop has a round owing to the use of the memory 3 of small capacity (64 bytes). Then the memory 3 has the hits at and after the 2nd round of the loop, and the microprocessor 1 is set in a waiting state. As a result, the waiting state of the microprocessor 1 is quickly and accurately detected and then switched to a stand-by mode. Then the power consumption of the microprocessor is reduced.
