摘要： An image processing system includes a first flip-flop bank and a second flip-flop bank, and a control system configured to control JPEG processing of image data. The control system is further configured to, during a first period, use one of the first or second flip-flop banks as a write bank and the other of the first or second flip-flop banks as a read bank and, during a second period, alternate the use of the first and second flip-flop banks as the write bank and the read bank. Further, the control system is configured to, after alternating the use, initialize the read bank to zero.

摘要： A computer-implemented method comprises receiving a data stream that includes a series of code words that encodes a respective series of pixel data according to a first entropy coding lookup table, and processing the data stream to determine if there is a match between a first code word and a consecutive second code word, and a code word entry in a second entropy coding lookup table. The method also includes, if there is a match, decoding the first code word and the second code word using the second entropy coding lookup table. Further, the method includes, if there is not a match, decoding the first code word using the first entropy coding lookup table.

摘要： Techniques and computing devices related to modifying images are provided. A computing device can receive an order to modify pixels of an image. The computing device can include at least a pixel processor and software snippets that are executable on the pixel processor. The computing device can determine parameter values based on the order. The computing device can select a set of software snippets from the software snippets based on the parameter values. The computing device can load the set of software snippets onto the pixel processor. The pixel processor can execute the loaded set of software snippets to modify the pixels. The computing device can generate an output that includes a depiction of the image that includes at least one of the modified pixels.

摘要： Example systems and related methods may relate to a synchronous first-in-first-out (FIFO) data buffer. The synchronous FIFO data buffer may include a counter. The counter may (i) receive a plurality of signals and (ii) output a count of total entries in the FIFO. The FIFO may further include a status generator that may (i) receive the plurality of signals and the count of total entries, and (ii) outputs a status signal. The FIFO may further include a selection generator that may (i) receive the count of total entries, the write signal, and the read signal, and (ii) output a data enable signal and a multiplexor selection signal. The FIFO may further include a scalable N×M flip-flop memory structure. N may be a number of entries in the memory structure and M may be a number of bits using flip-flops.
