摘要： A method and apparatus suitable for generating programmable digital sine waves which involves converting the output of a direct digital synthesizer or numerically controlled digital oscillator to a higher frequency with a multiplier-less structure that takes advantage of the properties of trigonometric identifies for sine and cosine. Sine waves are generated digitally using a phase accumulator which is clocked at one fundamental frequency. The phase accumulator input provides a control word which determines the intermediate frequency of the direct digital synthesizer output. Taking advantage of the periodicity of the phase accumulator operation, the outputs of the accumulator are utilized to address a read only memory ROM lookup table which produces in-phase and quadrature samples of the sine wave at the intermediate frequency. The in-phase and quadrature samples are then complemented (i.e. negated) to produce an additional set of in-phase and quadrature samples which are 180.degree. out of phase from the original samples. Switching between these four possible outputs at a higher fundamental clock frequency results in the translation of the intermediate frequency output to a higher frequency.

摘要： A gate bias circuit for a plurality of GaAs amplifier stages is a transistor coupled to a temperature compensation current received from a CMOS control stage. A plurality of pHEMPT amplifier stages are coupled to the gate bias circuit and to a control voltage which switches the amplifier stage. A selectively controlled stage pass transistor enables a current mirror between the gate bias circuit and each stage amplifying transistor. The penultimate pHEMPT amplifier stage is coupled to a CMOS amplifier. A CMOS circuit provides both the temperature compensation current by a proportional to absolute temperature (PTAT) circuit and the control voltage enabling each pHEMPT transistor to receive its input signal in combination with the gate bias voltage.

摘要： Techniques and structures relating to virtual graphics processing units (VGPUs) are disclosed. A VGPU may appear to software as an independent hardware GPU. However, two or more VGPUs can be implemented on the same GPU through the use of control structures and by duplicating some (but not all) hardware elements of the GPU. For example, additional registers and storage space may be added in a GPU supporting multiple VGPUs. Different execution priorities may be set for tasks and threads that correspond to the different supported VGPUs. Memory address space for the VGPUs may also be managed, including use of virtual address space for different VGPUs. Halting and resuming execution of different VGPUs allows for fine-grained execution control in various embodiments.

摘要： Various techniques for storing computer numbers such as floating-point numbers. In one embodiment, a data processing unit is configured to represent floating-point numbers using a first precision with a first number of bits and a second precision with a second number of bits, where the second number of bits is greater than the first number of bits. A floating-point type value may be set upon a memory store to indicate whether a first representation of a floating-point number uses the first or the second number of bits. A second representation of the floating-point number and the floating-point type value may be stored accordingly. In some embodiments, the second representation may correspond to the first representation with one or more bits shifted. This format may lead to memory power savings when reading from a memory location of the second precision when the result is indicated as the first precision.
