摘要： An FPGA functions as an activation mode setting circuit for loading activation data stored on a PROM into a circuit setting memory and setting an activation mode when activating the CPU. The FPGA outputs an activation mode setting signal to the CPU, and the CPU is activated in the set activation mode. After the CPU is activated, it follows predetermined processing steps, and performs a control operation to load the circuit setting data stored in a storage section into the circuit setting memory. Thus, the FPGA is constructed as a circuit having a desired function, and also constructed as an activation mode setting circuit when activating the CPU.

摘要： The object of the present invention is to use the same FIFO line memory for both enlargement and reduction during variable-magnification processing in the scan direction, allowing reduction in circuit board area, reduction in power consumption, and reduction in cost, and to provide an image processing apparatus that allows variable-magnification processing to be carried out such that the speed of a scanning unit that captures image data during variable-magnification processing in the cross-scan direction is constant. During processing to enlarge an image in the scan direction, image data travels from CCD circuit board, passing through gate b of selector, is written to and read from FIFO memory, and from gate b of selector is written to memory provided at variable magnification unit. At variable magnification unit, image data is read from memory a plurality of times in correspondence to enlargement ratio, changing the magnification of the image data. Furthermore, image data is output through gate a of selector to LSU unit. During processing to reduce an image, image data travels from CCD circuit board, passing through gate a of selector, is input to variable magnification unit where it is subjected to variable-magnification processing, passes through gate a of selector, is written to and read from FIFO memory, passes through gate b of selector, and is output to LSU unit.

摘要： A channel condition detecting unit detects a condition of a channel between a transmitting apparatus and a receiving apparatus, in accordance with a pilot signal. A reference check matrix employed for LDPC coding in the transmitting apparatus is stored in the check matrix reconstructing unit. The check matrix reconstructing unit reconstructs the reference check matrix in accordance with a detection result of the channel condition detecting unit. An LDPC decoding unit obtains a probability value of each of bits in the receive data by executing the LDPC decoding operation based on a check matrix supplied from the check matrix reconstructing unit, for a likelihood value of each of the bits in an encoded bit sequence input from a detecting unit. A hard decision unit subjects a probability value of each of bits in the receive data to hard decision and obtains the receive data.
