    • A wrapping burst read determination unit determines whether or not a read request is a request of a wrapping read. If the read request is the request of the wrapping read, a memory address conversion unit extracts a plurality of addresses that includes an address in which payload data requested by the read request is stored, and designates a read out order of data from the plurality of addresses extracted. If the read request is the request of the wrapping read, a first data holding unit inputs first data read out from an address to which a forefront position in the read out order has been designated among the plurality of addresses, and stores the first data. If the read request is the request of the wrapping read, a data alignment unit, inputs trailing data read out from an address to which an end position in the read out order has been designated, and extracts payload data and an ECC which are correlated with each other from the first data and the trailing data.
    • 包装突发读取确定单元确定读取请求是否是包装读取的请求。 如果读取请求是包装读取的请求,则存储器地址转换单元提取包括存储读取请求所请求的有效载荷数据的地址的多个地址,并且从多个地址指定数据的读出顺序 提取地址 如果读取请求是包装读取的请求,则第一数据保持单元输入从多个地址中指定了读出顺序中的前端位置的地址读出的第一数据,并存储第一数据。 如果读取请求是包装读取的请求,则数据对齐单元输入从已经指定了读取顺序中的结束位置的地址读出的尾随数据,并且提取与 从第一个数据和尾随数据彼此相交。

    • A multivalued input recording signal is to pulse-width modulation at a time unit shorter the period of a clock signal within the period of the recording signal. Alternatively, the multivalued input recording signal is converted into a plurality of different signals each of whose length of time is shorter than a clock signal within the period of the recording signal, thereby performing pulse-width modulation in accordance with a predetermined weighting. This makes it possible to obtain a highly toned recording signal without raising the frequency of the clock signal. Further, density tone data is generated in dependence upon inputted multivalued pixel data, control is performed using both the irradiation time and emission intensity of a light beam based on the generated density tone data. An image is formed by irradiating a photosensitive body with the controlled light beam.
    • 多值输入记录信号是在记录信号的周期内的时钟信号的周期短的时间单位进行脉宽调制。 或者,多值输入记录信号被转换成多个不同的信号,其长度在记录信号的周期内比时钟信号短,从而根据预定的加权进行脉冲宽度调制。 这使得可以在不提高时钟信号的频率的情况下获得高度调色的记录信号。 此外,根据输入的多值像素数据生成浓度色调数据,基于生成的浓度色调数据,使用光束的照射时间和发射强度两者进行控制。 通过用受控光束照射感光体形成图像。
