    摘要: Techniques are disclosed involving the transfer of signals across interconnection media. For instance, an apparatus may include a configuration module and a driver module. The configuration module may select one or more of multiple phase intervals within a time duration. This time duration may correspond to the time period length employed in a sequence of time periods. The driver module provides an interconnection medium with an output signal during one of the time periods. The output signal has an input signal level during the selected phase interval(s) of the period. During any remaining phase intervals of the time period, the driver module provides an alternate signal level.

    摘要: Digital signals are sent in a predetermined sequence from one end of a bus wire and are received at the other end. Each of the digital signals of the received sequence is compared with a corresponding predetermined signal of the predetermined sequence to determine whether an error has occurred. Data obtained concerning bus errors may be used to handle bus errors during runtime.

    摘要: In a computer graphics system, an address generator processes physical and virtual addresses using a common command set. The address generator formulates addresses as a function of distance from the origin of the desired destination area in a destination memory to the requested position in the destination area. A plurality of context drawing commands is used to define a desired context in which drawing graphics commands operate. Different parts of the context are changeable/redefinable independently of the other parts. Graphics commands have a format of multiple fields having corresponding parameters arranged in order of common use of the parameter such that fields of less commonly used parameters are at an omittable end of the format. Raster drawing commands are delimited by a beginning and end indicator to form a drawing unit. For clip list processing, a drawing unit is stored as a single occurrence in the system command buffer.

    摘要: In a computer graphics system, an address generator processes physical and virtual addresses using a common command set. A separate translator provides conversion from generated virtual addresses to physical addresses. The address generator formulates addresses as a function of distance from the origin of desired destination area in destination memory to the requested position in the destination area. A plurality of drawing graphics commands specify different raster drawing operations. A plurality of context graphics commands is used to define a desired context in which drawing graphics commands operate. The defined context includes destination location for resulting data, type and plane depth of graphics operations, foreground and/or background color of resulting data. Different parts of the context are changeable/redefinable independently of the other parts. The graphics commands have a format of multiple fields. Different fields specify different parameters. For each graphics command, the fields are arranged in order of common use of the corresponding parameter such that fields of less commonly used parameters are at an omittable end of the format. Thus, length of each graphics command varies as a function of parameters specified in the graphics command. A desired set of raster drawing commands delimited by a beginning indicator and an end indicator form a drawing unit.
