Patent number: 11861781Abstract: The graphics processing unit (GPU) of a processing system transitions to a low-power state between frame rendering operations according to an inter-frame power off process, where GPU state information is stored on retention hardware. The retention hardware can include retention random access memory (RAM) or retention flip-flops. The retention hardware is operable in an active mode and a retention mode, where read/write operations are enabled at the retention hardware in the active mode and disabled in the retention mode, but data stored on the retention hardware is still retained in the retention mode. The retention hardware is placed in the retention state between frame rendering operations. The GPU transitions from its low-power state to its active state upon receiving an indication that a new frame is ready to be rendered and is restored using the GPU state information stored at the retention hardware.Type: GrantFiled: December 28, 2020Date of Patent: January 2, 2024Assignees: SAMSUNG ELECTRONICS CO., LTD., Advanced Micro Devices, Inc., ATI TECHNOLOGIES ULCInventors: Sreekanth Godey, Ashkan Hosseinzadeh Namin, Seunghun Jin, Teik-Chung Tan

Patent number: 7783692Abstract: A method and circuit for fast flag generation. The circuit is coupled to receive data to be shifted, the data including a first plurality of bits. A shift count value (including a second plurality of bits) is also received by the circuit, as well as an indication of a direction the data is to be shifted. Based on the shift count value and the indication of direction, the position of a bit within the data is determined. The bit is then output as a flag bit.Type: GrantFiled: July 5, 2005Date of Patent: August 24, 2010Assignee: Advanced Micro Devices, Inc.Inventors: Wing-Shek Wong, Michael E. Tuuk, Teik-Chung Tan

Patent number: 7610476Abstract: Various embodiments of methods and systems for storing multiple groups of microcode operations and corresponding control sequences per row of microcode ROM are disclosed. In one embodiment, an integrated circuit may include a microcode ROM coupled to a control sequence logic unit. The microcode ROM may store multiple groups of microcode operations per row. For each group of microcode operations stored in a row, a corresponding control sequence may also be stored in the row. Each group of microcode operations may be included in a microcode routine. The groups of microcode operations stored in a row may be included in the same microcode routine, or some of the groups may be included in different microcode routines.Type: GrantFiled: December 5, 2003Date of Patent: October 27, 2009Assignee: Advanced Micro Devices, Inc.Inventors: Teik-Chung Tan, Gregory William Smaus

Patent number: 7584237Abstract: A method and mechanism for performing division. A processor includes a divider configured to perform arithmetic division operations. Prior to dividing a dividend by a divisor, the divider manipulates the dividend and divisor to reduce the number of bits considered and the computations required to perform the division. The divisor is normalized by eliminating sign bits. The dividend is prescaled to eliminate one or more sign bits. Prescaling of the dividend may not be precise as sign bits of the dividend may be shifted out as groups of bits, rather than individual bits. Prescaling of the dividend may be adjusted to account for the fact that the divider considers multiple bits of the dividend at a time. Subsequent to prescaling and adjustment, the dividend may be adjusted in dependence upon the normalization of the divisor. Further adjustment may be utilized to maintain a significance relationship between the divisor and dividend. Subsequent to further adjustment, the division operation may be completed.Type: GrantFiled: October 11, 2005Date of Patent: September 1, 2009Assignee: Advanced Micro Devices, Inc.Inventors: Teik-Chung Tan, Michael Tuuk, Wing-Shek Wong
