    摘要: A semiconductor device includes a time-to-digital converter (TDC) that receives a reference frequency signal and a feedback frequency signal, and outputs a first digital signal indicating a time difference between the reference frequency signal and the feedback frequency signal; a digital loop filter (DLF) that outputs a second digital signal generated by filtering the first digital signal; a multiplier circuit that outputs one of a third digital signal and a final test signal, the third digital signal generated by performing a multiplication operation on the second digital signal using a multiplication coefficient; a digital-controlled oscillator (DCO) that generates an oscillation signal having a frequency based on the output one of the third digital signal and the final test signal; and a loop gain calibrator (LGC) that receives the oscillation signal, generates a pair of test signals, and determines the multiplication coefficient using the pair of test signals.

    摘要: A secure processor and a semiconductor system including the same is provided. Provided is a system on chip comprising a secure processor, wherein the secure processor includes: a random access memory (RAM) including a RAM cache area storing a page and a timestamp table storing a timestamp, an encryption/decryption engine configured to encrypt the page by using the timestamp, and a direct memory access (DMA) module configured to transmit the encrypted page to a swap area of a first memory disposed outside the system on chip, wherein the first memory includes a tag table area storing a tag generated by the encryption/decryption engine encrypting the page and a timestamp backup area backing up the timestamp, and the swap area, the tag table area, and the time stamp backup area are backed up in a second memory disposed outside the system on chip.
