    • Methods and apparatuses for concurrently recording multiple radio channels. A recorder includes a wideband tuner having a complex mixer for converting a received wideband RF signal to a complex signal that is then digitized. A digital front end module applies a number of complex down-mixers to the digital complex signal to generate the multiple radio channels in the baseband. Each one of the multiple radio channels in the baseband is further filtered, decimated and demodulated. A digital signal processing unit encodes each demodulated channel according to an audio compression format and stores the then encoded audio content to a storage unit. An RBDS decoder parses radio data service information associated with the stored audio content. The radio data service information is stored in a first section of the storage unit while the encoded audio content is stored in a second section of the storage unit.
    • 同时记录多个无线电频道的方法和装置。 记录器包括具有用于将接收到的宽带RF信号转换成然后被数字化的复信号的复合混频器的宽带调谐器。 数字前端模块将数个复数下混频器应用于数字复合信号,以在基带中生成多个无线电信道。 基带中的多个无线电信道中的每一个被进一步滤波,抽取和解调。 数字信号处理单元根据音频压缩格式对每个解调的信道进行编码,并将所编码的音频内容存储到存储单元。 RBDS解码器解析与所存储的音频内容相关联的无线电数据服务信息。 无线电数据服务信息被存储在存储单元的第一部分中,而编码的音频内容被存储在存储单元的第二部分中。

    • A method and system for performing an auction by determining a request for an item based on at least one of (i) an item to purchase, (ii) a performance specification of the item to purchase, and (iii) a term of a request for the item to purchase. The method and system include sending, through a network, the request for the item to an auctioneer machine server. Performance information is collected for each seller. Notice is provided that a performance evaluation has been received for a specific seller, and is on record with the provider of the information. Additional transaction costs may be captured and included as a separate line item in an auto-rebid auction environment.

    • A three input arithmetic logic unit (230) forms a mixed arithmetic and Boolean combination of three multibit input signals. The arithmetic logic unit (230) first forms a Boolean combination and then forms an arithmetic combination. The current instruction drives an instruction decoder (250, 245) that generates the functions signals F0-F7 which control the combination formed. The three input arithmetic logic unit (230) preferably employs a set of bit circuits (400), each forming carry propagate, generate and kill signals. These signals may employed with a multilevel logic tree circuit and a carry input to produce a bit resultant and a carry output to the next bit circuit. This structure permits formation of selected arithmetic, Boolean or mixed arithmetic and Boolean function of the three input signals based upon the current instruction. Selection of the function signals enables the combination to be insensitive to one of the input signals, thus performs a two input function of remaining input signals. The instruction itself may include the function signals and function modification bits, or the function signals and function modification signals may be stored in a special data register. Function modification signals cause modification of the function signals prior to use. The three input arithmetic logic unit (230) includes a least significant bit carry-in generator (246) supplying a carry input to the least significant bit. This carry input is determined by the combination being formed, and generally is "1" only during subtraction. The carry input may be specified in the special purpose data register (D0) for certain instructions. The combination formed is optionally modified dependent upon the sign bit of one of the inputs.
    • 三输入算术逻辑单元(230)形成三个多位输入信号的混合运算和布尔组合。 算术逻辑单元(230)首先形成布尔组合,然后形成算术组合。 当前指令驱动产生控制所形成的组合的功能信号F0-F7的指令译码器(250,245)。 三输入算术逻辑单元(230)优选地采用一组比特电路(400),每一组形成进位传播,产生和终止信号。 这些信号可以与多级逻辑树电路和进位输入一起使用,以产生位结果和进位输出到下一位电路。 该结构允许基于当前指令形成三个输入信号的所选算术,布尔或混合运算和布尔函数。 功能信号的选择使得组合对输入信号之一不敏感,从而执行剩余输入信号的两个输入功能。 指令本身可以包括功能信号和功能修改位,或者功能信号和功能修改信号可以存储在特殊数据寄存器中。 功能修改信号在使用前会引起功能信号的修改。 三输入算术逻辑单元(230)包括向最低有效位提供进位输入的最低有效位进位发生器(246)。 该进位输入由形成的组合确定,并且通常在减法期间为“1”。 某些指令可以在专用数据寄存器(D0)中指定进位输入。 根据其中一个输入的符号位可选地修改形成的组合。

The current instruction drives an instruction decoder (250, 245) that generates the functions signals F0-F7 which control the combination formed.

The first Boolean combination F1(A,B,C) and the second Boolean combination F2(A,B,C) are independently selected from the set of all possible Boolean combinations of three multibit input signals A, B and C. The adder (495) includes a least significant bit carry-in generator (246) supplying a carry input to the least significant bit.
