摘要： A method of compiling a computer program to improve trace efficiency is disclosed. The computer program comprises a plurality of trace operations for triggering output of trace data generated by said computer program, and the method of compiling comprises the steps of: transforming said computer program into code forming an intermediate version of said computer program; analysing said transformed code; replacing at least some of said trace operations with modified trace operations; transforming said code into code suitable for execution on a data processing system; and generating translation data relating said modified trace operations to said trace operations they replaced.

摘要： An asymmetric multiprocessor apparatus 2 is provided in which respective slave diagnostic units 20, 22, 24 are associated with corresponding execution mechanisms 6, 8, 10. A master diagnostic unit 26 tracks the migration of thread execution between the different execution mechanisms 6, 8, 10 so that the execution of a given thread can be followed by the diagnostic mechanisms 20, 22, 24, 26 and this information provided to the programmer. The execution mechanisms 6, 8, 10 can be diverse such as a general purpose processor 6, a DMA unit 12, a coprocessor, an VLIW processor, a digital signal processor 8 and a hardware accelerator 10. The asymmetric multiprocessor apparatus 2 will also typically include an asymmetric memory hierarchy such as including two or more of a global memory, a shared memory 16, a private memory 18 and a cache memory 14.

摘要： A computer implemented tool is provided for assisting in the mapping of a computer program to a data processing apparatus wherein multiple physical instances of a logical variable in the computer program are required. A computer program is provided as the input to the tool which analyses the data flow of the program and identifies multiple physical instance requirement for logical variables. The tool adds mapping support commands, such as instantiation commands, Direct Memory Access (DMA) move commands and the like as necessary to support the mapping of the computer program to a data processing apparatus.
