摘要： A method of performing a processing task in a data processing apparatus is provided that reduces memory usage of the processing task. According to this method a Virtual Machine performs the steps of accessing platform-neutral program code in a function repository, executing the processing task on the Virtual Machine, and analysing at a current execution point, on a function-by-function basis, which functions in the function repository are inactive functions. The Virtual Machine performs software-based unloading from the function repository of at least a portion of platform-neutral program code corresponding to one or more inactive functions. A corresponding virtual machine and data processing apparatus are also provided.

摘要： A trusted content usage monitor for monitoring content usage is provided. A unique identifier generation unit generates a unique identifier indicative of content being rendered and a packet generator generates a trusted packet comprising the unique identifier. The trusted packet is trust signed by the trusted content usage monitor, so that it can be trusted by its recipient. The trusted content usage monitor has at least one mode of operation in which content rendering cannot be decoupled from operation of the unique identifier generation unit, so that generated packets can be trusted as truly indicative of content usage.
摘要翻译：提供了用于监视内容使用情况的受信任的内容使用监视器。唯一标识符生成单元生成指示被呈现的内容的唯一标识符，并且分组生成器生成包括唯一标识符的信任分组。受信任的信息包是由受信任的内容使用监视器进行信任的签名，以便它被其接收方信任。信任内容使用监视器具有至少一种操作模式，其中内容呈现不能与唯一标识符生成单元的操作解耦，使得生成的分组可以被信任为真实地指示内容使用。

摘要： A data processing apparatus and method are provided for tracing activities of a shader program executed on shader circuitry of a data processing apparatus. The data processing apparatus comprises shader circuitry which is responsive to input data for a pixel to execute a shader program to generate a colour value for the pixel. The shader program has multiple execution paths via which the colour value may be generated, and which execution path is taken is dependent on the input data. An image buffer having a plurality of storage locations is provided, with each storage location being used to store the colour value generated by the shader circuitry for an associated pixel. In a trace mode of operation, execution of the shader program by the shader circuitry causes a trace vector to be generated containing a plurality of items of execution path information indicative of the execution path taken, the trace vector comprising a plurality of fields, each field being used to store one item of execution path information. The trace vector as output is constrained to be of the same size as the colour value, and in the trace mode of operation the trace vector is stored in one of the storage locations of the image buffer in place of the colour value generated by the shader program. This has been found to provide an efficient mechanism for obtaining execution path data useful when performing a variety of debugging activities in respect of a shader program.
摘要翻译：提供了一种用于跟踪在数据处理装置的着色器电路上执行的着色器程序的活动的数据处理装置和方法。数据处理装置包括着色器电路，其响应于像素的输入数据来执行着色器程序以生成像素的颜色值。着色器程序具有多个执行路径，通过该路径可以生成颜色值，并且执行路径取决于输入数据。提供具有多个存储位置的图像缓冲器，其中每个存储位置用于存储由着色器电路为相关联的像素生成的颜色值。在跟踪操作模式中，着色器电路执行着色器程序导致生成跟踪向量，该跟踪向量包含指示所执行路径的多个执行路径信息项，跟踪向量包括多个场，每个场用于存储一个执行路径信息项。作为输出的跟踪向量被约束为与颜色值相同的大小，并且在跟踪操作模式中，跟踪向量存储在图像缓冲器的存储位置之一中，而不是由着色器生成的颜色值程序。已经发现，为执行关于着色器程序的各种调试活动时获得有用的执行路径数据提供了一种有效的机制。
