    摘要: Operation of a clock generating circuit is stopped when the oscillation signals to be selectively transmitted to the clock generating circuit via a multiplexer are switched. The oscillation signals are generated by a first oscillation circuit at a relatively high frequency and by a second oscillation circuit which steadily oscillates at a relatively low frequency. The clock generating operation is resumed in synchronization with the switched oscillation signals.

    摘要: A semiconductor integrated circuit system having a function of automatically adjusting an output resistance value with reference to a temperature of an LSI which is operating. When a count value obtained from a counter by counting the output of a timer becomes equal to a predetermined value, a temperature sensor measures temperatures of LSIs. If a temperature fluctuation measured from a previous measured value is greater than a predetermined width, then a control apparatus issues an output resistance value adjustment request signal to output resistance adjustment units of the LSIs. When receiving the output resistance value adjustment request signal, the output resistance value adjustment units stop the signal transmission between the LSIs, adjust output resistance values of output circuits in such a manner that the output resistance values are matched with a characteristic impedance of a transmission line, and maintains the adjusted output resistance values until the output resistance value adjustment units receive next output resistance value adjustment request signal.

    摘要: A semiconductor integrated circuit comprising a clock pulse generator, peripheral function blocks and bus master modules. The peripheral function blocks are commonly supplied with a first system clock signal of a constant frequency generated on the basis of the output from the clock pulse generator. The bus master modules are fed with a second system clock signal generated on the basis of the pulse generator output. The frequency of the second system clock signal is variable and lower than that of the first system clock signal. The function blocks supplied with the first system clock signal are connected to a data bus separate from the one connected to the function blocks fed with the second system clock signal.

    摘要: A method of controlling a cache memory disposed between a CPU and a main memory, wherein pairs of data and an address to be written in the cache memory are stored into a buffer memory. A plurality of pairs of data and an address read from the buffer memory are processed to compare the address fields thereof. Based on results of the comparisons, there is determined a write control for writing the data in the cache memory which has been subdivided into a plurality of banks. As a result, the plural pairs of data and an address are written into the plural banks of the cache memory, the addresses of the respective pairs being different from each other. With the provisions set forth above, the write operation can be independently conducted for each bank of the cache memory, thereby improving the write throughput.
