Abstract: A programming algorithm reduces from &thgr; (2N2) to &thgr; (N2) the number of multiply-and-accumulate (MAC) instructions required to perform a discrete-time convolution on a programmable digital signal processor. Through the use of a single repeat instruction along with a single repeat count register, the algorithm dynamically changes the number of times the multiply-accumulate instruction is repeated depending upon the current term being convolved. The avoids performing the multiply-accumulate when one term is zero. The nature of the discrete-time convolution calculation and the flexibility of a re-programmable single repeat count register offers permits this. Additional instructions are required for data pointer alignment. The trade-off between reduced multiply-accumulate operations and the overhead required to achieve it is examined.

Abstract: A runtime architecture for web services utilizes a container driver to accept an invoke request for web services, such as from a protocol adapter. The container driver performs any necessary data binding and unbinding required to process the invoke request and associated message context, utilizing an appropriate plugin component. An interceptor receives the context information from the container driver and modifies the message context for web service compatibility. An invocation handler receives the formatted context information from the container driver and passes parameters from the message context to the target of the request. The invocation handler processes values returned from the target and passes these values to the container driver. The container driver can then formulate a response to the invoke request, and return the response and message context to the client or protocol adapter.

Abstract: A recipient computer system submits an anonymous electronic message address to a source computing system for use when the source computing system is to send electronic messages to the recipient. When the electronic message server receives an electronic message, it reads the electronic message address and determines that the address corresponds to the recipient, but only if the electronic message originated from the source. If the electronic message were to originate from a different source computing system, the same electronic message address would not be respected for delivery to the recipient. Accordingly, the electronic message address is specific to a source, and thus sharing the electronic message address has little avail. The association between the address and the recipient may be revoked when the recipient no longer desires to receive messages from the source.
