Abstract: A co-processor system and a method for loading an application to a local memory of a co-processor system. In the method, re-locatable code and descriptive data are copied from a loading region to a non-loading region. An executable image to be loaded is loaded using the re-locatable code copied to the non-loading region according to the descriptive data. The local memory includes a loading region and a non-loading region, the loading region stories a loader and descriptive data of an executable image to be loaded of the application, and the loader includes re-locatable code. A system is provided for carrying out the steps of the method. In accordance with the system and method of the present invention, flexibility of co-processor system application development is improved without occupying additional storage space.

Abstract: Reducing runtime coherency checking using global data flow analysis is provided. A determination is made as to whether a call is for at least one of a DMA get operation or a DMA put operation in response to the call being issued during execution of a compiled and optimized code. A determination is made as to whether a software cache write operation has been issued since a last flush operation in response to the call being the DMA get operation. A DMA get runtime coherency check is then performed in response to the software cache write operation being issued since the fast flush operation.

Abstract: Simplifying transmission in a distributed parallel computing system. The method includes: identifying at least one item in a data input to the parallel computing unit; creating a correspondence relation between the at least one item and indices thereof according to a simplification coding algorithm, where the average size of the indices is less than the average size of the at least one item; replacing the at least one item with the corresponding indices according to the correspondence relation; generating simplified intermediate results by the parallel computing unit based on the indices; and transmitting the simplified intermediate results. The invention also provides a system corresponding to the above method.

Abstract: Compiler analysis and runtime coherency checking for reducing coherency problems is provided. Source code is analyzed to identify at least one of a plurality of loops that contains a memory reference. A determination is made as to whether the memory reference is an access to a global memory that should be handled by at least one of a software controlled cache or a direct buffer. A determination is made as to whether there is a data dependence between the memory reference and at least one reference from at least one of other direct buffers or other software controlled caches in response to an indication that the memory reference is an access to the global memory that should be handled by either the software controlled cache or the direct buffer. A direct buffer transformation is applied to the memory reference in response to a negative indication of the data dependence.

Abstract: An encoding method and an encoder for encoding data transmitted in a manner of bursts via a parallel bus and a decoding method and a decoder. The encoding method includes organizing data of the bursts into matrixes, determining for each of the matrixes whether a transform mode capable of decreasing the bus transition number exists, determining that the matrix needs to be transformed, determining a transform mode for transforming the matrix, and replacing the initial matrix with the transformed matrix. Then, forming a new matrix to be transmitted from matrixes which do not need to be transformed and matrixes which have been transformed. Thereafter, first generating a transform information word indicating transform states of the respective matrixes and then attaching the transform information word to the matrix to be transmitted to form an encoded matrix for actual transmission.
