摘要： A data processing apparatus and method for generating constant values is provided. The data processing apparatus comprises a data processing unit operable in response to an instruction to perform a data processing operation on one or more data values. Shift logic is operable to selectively apply a shift operation to data to produce one of the data values for the data processing operation. Further, a plurality of registers are provided for storing data. The instruction has a register specifier field for identifying a register and a shift specifier field for specifying a shift to be applied to that register's data in order to produce one of the data values for the data processing operation. The register specifier field is allocatable a distinguished value, and if the register specifier field has that distinguished value, the shift logic is provided with a predetermined value and generates therefrom one of a plurality of constant values dependent on the shift specified by the shift specifier field, the generated constant value then being used as one of the data values for the data processing operation.

摘要： A data processing apparatus operable to form a graphics image is disclosed. The apparatus comprises a data store for storing an object list of objects to be displayed within said graphics image; a colour buffer operable to store a plurality of pixels to be displayed as said graphics image; a depth buffer operable to store a depth value corresponding to a distance of a pixel within said colour buffer from a front or viewing plane of said graphics image; a plurality of data processors operable to process data in parallel, each of said plurality of data processors being operable to: derive a pixel value of an object from said object list; access a depth buffer value stored in said depth buffer at a position corresponding to said pixel and to replace it with a lock value and in response to said accessed depth buffer value not being said lock value, to: compare a depth of said pixel value with said accessed depth buffer value; and either in response to said comparison indicating said pixel value being closer to a viewing plane of said graphics image than said accessed depth buffer value said data processor is operable to write said pixel value to a corresponding position in said colour buffer and subsequently replace said lock value in said corresponding position in said depth buffer with a depth of said pixel value; or in response to said comparison indicating said object being further from said viewing plane of said graphics image than said accessed depth buffer value said data processor is operable to replace said lock value in said corresponding position in said depth buffer with said accessed depth buffer value.

摘要： A method and data processing apparatus for assisting a user when preparing assembly language source code to be executed by a processor core is provided. The assembly language source code comprises a sequence of assembly language instructions. The method comprises the steps of: receiving an assembly language instruction entered by the user; determining, with reference to a model representing the operation of the processor core when executing the sequence of assembly language instructions, whether a predetermined condition will occur due to a relationship between the assembly code instruction and at least one other assembly code instruction in the sequence of assembly language instructions which will cause the processor core to operate in an undesirable manner; and if the predetermined condition occurs, displaying to the user an indication of the relationship between the assembly code instruction and the at least one other assembly code instruction which will cause the processor core to operate in the undesirable manner. Providing such an indication assists the user when preparing the assembly language source code by alerting him to the fact that the performance of the code when being executed on the processor core may not be as high as may be possible.
