摘要： A digital log gain to digital linear gain multiplier is disclosed. The digital log gain to digital linear gain multiplier includes a log gain splitter adapted to split a log gain input into an integer log part and a remainder log part. A log scale-to-linear scale converter is adapted to output a linear gain value in response to the integer log part and the remainder log part. A gain multiply circuit is adapted to multiply a digital signal by the linear gain value to output a gain-enhanced digital signal.

摘要： Line coding, or data coding at the physical layer of transmission, storage and retrieval has typically been previously by a digital representation of the actual binary coded value of a positional data bit in a byte. Bits are constructed into bytes of eight bits, words are constructed of two bytes, and so forth. Each more significant bit positional location in a typical eight bit byte is of greater value by a factor of two. This method of data coding is pervasive throughout modern information technology related devices, equipment and processing systems. In one embodiment of the invention—at bit location following that of 24—the bit value of the bits in a byte or larger data word structure increase by double the exponent of the previous binary digit value. In another embodiment of the invention—at bit location following that of 24—the bit value of the bits in a byte or larger data word structure increase to the square of the exponent of the previous binary digit value. Invented format enables massively more digital data easily be represented, stored, retrieved or transmitted by just one byte, word or larger data structure.

摘要： Large integers may be stored according to byte-stable variable-length encoding systems and methods, eliminating the need to store many leading-zero bits in large integers. Such a byte-stable variable-length integer encoding scheme may represent identical sequences of numbers in a consistent byte pattern within a byte stream, preserving the redundancy of the data and allowing for improved compression rates.

摘要： The invention is related to a method for encoding a size of a data section and to an encoder for encoding a size of a data section. The invention is further related to a method for determining a size of a data section and to a decoder for determining a size of a data section. The method for encoding a size of a data section comprises the step of increasing the size and the step of determining the number of information units necessary for encoding the increased size. Furthermore, the method comprises the step of decreasing the determined number and the step of forming a code by encoding the decreased determined number and by encoding the increased size. Due to knowledge of an increased lower bound, instead of the number of information units actually necessary for encoding the size a decreased number can be encoded.

摘要： Techniques for coding integer sets are described herein. According to one embodiment, for each data range of parameters to be encoded, a number of bits required to represent a maximum parameter among the parameters in each data range is determined, including a first number of bits and a second number of bits corresponding to the first and second data ranges. Each parameter in the first data range is encoded using the first number of bits and each parameter in the second data range is encoded using the second number of bits, where the data stream further includes a value representing the first number of bits and the data stream is to be decoded by a decoder using the value representing the first number of bits to recover the first number of bits and the second number of bits, which are used to recover each parameter from the data stream.

摘要： In a more effective data generation method and circuit used for 64B/66B encoding, when packet data, and head and tail information of the data packet are received, write user data in which a head and tail identifying bytes are respectively added to a head and a tail of the packet data based on the head and tail information is associated with control data indicating positions of both of the identifying bytes to be written in a memory sequentially from a predetermined address of the memory. From the predetermined address, user data by 8 bytes and the control data corresponding to the user data are sequentially read to be provided to a 64B/66B encoding circuit. During a period in which the reading can not be made, idle bytes for 8n bytes (n≧1) and control data indicating the idle bytes, or maintenance user data of 8n bytes (n≧2) in which the head and tail identifying bytes are respectively added to a head and a tail of the maintenance information and control data indicating positions of both of the identifying bytes are provided to the 64B/66B encoding circuit.

摘要： Passing input strings through an application programming interface between functions that take null byte terminated strings as arguments, where at least some of said input strings contain null bytes internally. This is accomplished by storing the positions of the null bytes relative to the start of the block and storing the non-null bytes in their relative order to prevent said internal null strings from being treated as terminal null strings.

摘要： A data converter, or “gearbox,” for a padded protocol interface can perform a number of different conversions—e.g., between 64 and 66 bits, between 24 and 26 bits, or between 48 and 50 bits. This is accomplished by clocking the gearbox at different clock speeds, all derived from the same master clock (which may be recovered from the data in a receiver embodiment) using programmable dividers that allow the user to select the clock speed. When the conversion is not that one with the maximum width for which the gearbox is designed, unused bits are ignored. The converter can also find padding bits, for alignment purposes, in data of different widths, again ignoring unused bits when the data are not the widest for which the converter is designed.

摘要翻译： 用于填充协议接口的数据转换器或“变速箱”可以执行多个不同的转换，例如在64位和66位之间，在24位和26位之间，或在48位和50位之间。 这是通过使用可允许用户选择时钟速度的可编程分频器从不同时钟速度对齿轮箱进行计时的，这些时钟速度全部来自相同的主时钟（可以从接收机实施例中的数据恢复）。 当转换不是设计齿轮箱的最大宽度的转换时，未使用的位将被忽略。 转换器还可以在不同宽度的数据中找到用于对齐目的的填充位，当数据不是设计转换器的最宽时，再次忽略未使用的位。
