摘要： A fixed-size codeword table is generated for decompressing GIF encoded data. The fixed-size codeword table is defined to store a codeword string and a codeword length for each of a number of codewords. The codeword string is defined by a codeword previously represented in the codeword table and a character. The codeword length represents a total number of characters in the codeword string. A current codeword in the GIF encoded data is translated according to the codeword table to generate a series of characters represented by the current codeword. The generated series of characters is stored in a computer memory space.

摘要： An interface between a host and a slave device having a latency greater than the latency of the host is disclosed. The interface includes a register and a state machine. The state machine provides data to the host from any address in the slave in two host read cycles. The state machine receives a first request from the host for data stored at a first address in the slave at a first time. The state machine stores the data returned from the slave in response to the first request in the register at a second time. The state machine receives a second request from the host for data stored at a second address in the slave at a third time. The state machine provides the data specified in the first request to the host at a fourth time. The state machine is additionally adapted to provide data to the host from a second address in the slave in one read cycle.

摘要： A power cut-off protection control circuit and method. A memory pair and a selecting circuit are provided. The memory pair stores data made available at respective storage inputs of first and second storage elements of the pair and provides the stored data at respective storage outputs thereof. The memory pair has a polarity selecting input through which the output of one of the first and second storage elements is caused to correspond to a first control state of the switch and the output of the other of the first and second storage elements is caused to correspond to a second control state of the switch. The selecting circuit has inputs coupled to the respective storage outputs of the memory pair and an output coupled to a control line of the switch for controlling the switch. A selecting line of the selecting circuit selects between the inputs, for selecting one or the other of the storage outputs of the first and second storage elements.
