摘要
PURPOSE:To shorten a system rise time by checking whether a memory test skip instruction exists or not, in a memory test period, discontinuing its memory test, when it has become significant, and shifting the processing to an IPL. CONSTITUTION:When a power source of a system is turned on, an operating test of a principal LSI and its initializing are executed, and if it is normal, a memory test is executed. When executing the memory test, 16k bytes are one block, data is written (Write) to an effective memory size, its data is read out (Read), and this Read/Write data is compared. In this case, a key input for detecting a memory error and a memory test skip is checked at every 16k bytes. When checking the key input,, an interruption, etc. are used, whether the key input exists or not is checked by reading the contents of a specified flag (register area 23), and when the key input is detected, the memory test is discontinued, and the processing is shifted to an IPL.
