Abstract:
The present invention relates to a platform power management scheme. In some embodiments, a platform provides a relative performance scale using one or more parameters to be requested by an OSPM system.
Abstract:
A method, system, and computer usable program product for improved register allocation in a simultaneous multithreaded processor. A determination is made that a thread of an application in the data processing environment needs more physical registers than are available to allocate to the thread. The thread is configured to utilize a logical register that is mapped to a memory register. The thread is executed utilizing the physical registers and the memory registers.
Abstract:
A register file, in a processor, includes a first plurality of registers of a first size, n-bits. A decoder uses a mapping that divides the register file into a second plurality M of registers having a second size. Each of the registers having the second size is assigned a different name in a continuous name space. Each register of the second size includes a plurality N of registers of the first size, n-bits. Each register in the plurality N of registers is assigned the same name as the register of the second size that includes that plurality. State information is maintained in the register file for each n-bit register. The dependence of an instruction on other instructions is detected through the continuous name space. The state information allows the processor to determine when the information in any portion, or all, of a register is valid.

Abstract:
Example embodiments for configuring a serial non-volatile memory device for an execute-in-place mode may comprise a non-volatile configuration register to store an execute-in-p!ace mode value that may be read at least in part in response to power being applied to the memory device.
Abstract:
An instruction set for a microcontroller with a data memory divided into a plurality of memory banks wherein the data memory has more than one memory bank of the plurality of memory banks that form a block of linear data memory to which no special function registers are mapped, a bank select register which is not mapped to the data memory for selecting a memory bank, and with an indirect access register mapped to at least one memory bank, wherein the instruction set includes a plurality of instructions operable to directly address all memory locations within a selected bank, at least one instruction that provides access to the bank select register, and at least one instruction performing an indirect address to the data memory using the indirect access register.
Abstract:
Systems and methods are provided for managing access to registers. A system may include a set of direct registers and a set of indirect registers. The indirect registers may be accessed through the direct registers, and the direct registers may provide various features to provide faster access to the indirect registers. One of the direct registers may indicate access modes for accessing the indirect registers. The access modes may include auto-increment, auto-decrement, auto-reset, and no change modes. Based on the access mode, the currently accessed address may be automatically modified after accessing the indirect register at the address.
Abstract:
A method includes identifying a first register with M bits and a second register with N bits. The process also includes shifting K bits, where K
Abstract:
An extension to current multiple memory bank (309) video processing architecture is presented. A more powerful memory controller (310, 311) is incorporated, allowing computation of multiple memory addresses at both the input and the output data paths (316) making possible new combinations of reads and writes at the input and output ports. Matrix transposition computations required by the algorithms used in image and video processing are implemented in MAC modules and memory banks. The technique described here can be applied to other parallel processors including future VLIW DSP processors.
