摘要： PURPOSE:To prevent a precharge level of a data line from being increased undesirably by interposing a power switch transistor (TR) between both power terminals to supply a power voltage to a sense amplifier. CONSTITUTION:During precharge period, power switch MOSFETs Q18, Q19 are cut off. Thus, complementary bit lines BLi, the inverse of BLi are precharged to a comparatively lower level than the power voltage Vdd during the precharge period. Thus, even if the gate voltage of the P-channel MOSFET Q16 receiving the level at its gate is lower than the voltage Vdd, since the power switch MOSFET Q18 is cut off, the voltage Vdd is supplied from a sense amplifier 22 to the bit lines BLi, the inverse of BLi thereby preventing undesired precharge level increase. Thus, the bit lines BLi, the inverse of BLi keep a level specified by the precharge circuit 21.

摘要： PURPOSE:To contrive the high speed of a processing to calculate the continuous length of the same color picture elements by converting run length data into address signals with a converting means to be hardware, and accessing a memory. CONSTITUTION:A means 11 is provided which generates the run length data to apply the continuous length from a change point to the next change point in the respective picture element data on a scanning line in the range from a minimum value to a maximum value. Run length data RL4 to RL15 outputted from the run length data generating means 11 are converted and generated to memory address signals MA1 to MA9 for a RAM10 by a converting means 12. Consequently, when the number of the picture elements included in one scanning line is >=the memory capacity of the RAM 10, since the number of the exchange of the data for the RAM10 is taken into consideration, and the continuous length is calculated, a software processing is made unnecessary. Thus, the processing to calculate the continuous length of the same color picture elements can be shortened by a time consumed for such a software processing as usual.

摘要： PURPOSE:To suppress the increase in the number of circuits and to localize a defective place by storing a testing program in addition to programs which are essentially necessary for the operation of an LSI, and utilizing an essentially necessary means for testing. CONSTITUTION:A parameter (f) provided for the original purpose of switching internal processing formats, signals such as a strobe pulse (g) for the parameter (f), and a microcomputer interface 2 are used for test/nontest processing mode switching and processing mode specification for switching contents of a test. For this purpose, a control input terminal is added to an LSI element, and the new test program is stored in a memory 4 for program storage in addition to programs for attaining the original functions of the LSI. The essential parameter (f) for matching format switching is used for switching test contents, and an external RAM stored with the progress of a matching value necessary originally for matching processing is used to confirm such as the fetch of input data, localizing defective parts.
