However, the full capability of the interface may not be necessary in all systems. As a result, they are quite sensitive to performance degradation. The algActivate( ) function provides a notification to the algorithm instance that one or more algorithm processing functions is about to be run zero or more times in succession. Next, in step 2404, the specific module interface, the IG723ENC interface, must be created. The calling program then allocates a portion of memory to each algorithm module to instantiate each instance in accordance with the memory usage requirement identified by the memory interface of each algorithm module. Since interfaces may build atop other interfaces, all header files are required to allow for the possibility that they might be included more than once by a framework. To avoid having to make changes to source code, only one header file must suffice for all variants supplied by a vendor. Algorithm developers will structure their implementations to take advantage of the available memory spaces to optimize performance. Two other execution paths are available to the framework, as illustrated by arrows 809 and 810. Associated with the compiler will be language run-time support that will be incorporated into an application when it is constructed with the linker. The first argument to algAlloc( ) is a pointer to the creation arguments for the instance of the algorithm object to be created. The trace levels specified in the mask are enabled for this instance. strings of text saved by a browser on the user's device. No. In an ideal world, a module that implements an API can be used in any system that requires the API. Multithreading is the management of logically concurrent threads within the same program, or system. This static memory allocation is then initialized at run-time. A filter group object simply maintains global state. Memory management address translation . However, it is important to realize that algMoved( ) is called in real-time whereas alginit( ) is not. RTC_init( ) is called during system startup to perform any run-time initialization necessary for the RTC module as a whole. A static system is one in which no memory allocation occurs at run-time. 8. RTC_enable returns nothing. However, unlike general-purpose embedded microprocessors, DSPs are designed to run sophisticated signal processing algorithms and heuristics. However, other implementation specific operations can also, = = = = = = = = FIR_TI_Handle = = = = = = = =. Since IG723ENC_Fxns extends IALG_Fxns, the IG723ENC v-table must also include the functions in the IALG v-table as shown in Table 28. algDeactivate( ) can only be called after a successful return from algInit( ). 3 In addition, the module should declare a static constant structure named XYZ of type XYZ_Config that contain the module's current configuration parameters. In this model, all physical memory is partitioned into two groups: scratch and persistent. 19 is a code listing of an example a uniform trace and diagnostic (IRTC) interface for an algorithm module in an alternative embodiment of the component model of FIG. In this embodiment, this functionality is provided by implementing the functions algActivate( ), algDeactivate( ), and algMoved( ). The C compiler supports a pragma directive that allows specified functions to be placed in distinct COFF sections. It also supports dynamic or run-time creation of those instances. and functions used to programmatically interact with a piece of software. The memory interface of the above embodiment informs the framework of the amount of memory required by the algorithm module. However, this pointer may be NULL. log must be a valid pointer to an object managed by the LOG module. This structure is initialized using the algorithm object and a pointer to a module's IRTC implementation functions. The portal can access those files and use them to remember the user's data, such as their chosen settings (screen view, interface language, etc. Thus, it is easy to use this module in multi-channel applications or in single channel applications that require more than one FIR filter. Embedded system 2. 7A). ALG_delete( ) deletes the dynamically created object indicated by its only argument. This abstract interface is called IALG. FIR_TI_filter((IFIR_Handle)handle, in, in); fir_ti_irtc.c - Vendor Specific Implementation of IRTC Interface, = = = = = = = = fir_ti_irtc.c = = = = = = = =, Filter Module IRTC implementation - TI's implementation of the, IRTC interface for the FIR filter algorithm, = = = = = = = = FIR_TI_rtcOut = = = = = = = =, = = = = = = = = FIR_TI_rtcBind = = = = = = = =. algAlloc( ) may be called at any time and it must be idempotent; i.e., it can be called repeatedly without any side effects and always returns the same result. To improve readability, use title case; for example, LOG_getBuffer ( ) should be used in lieu of LOG_get_buffer ( ). This static structure, referred to subsequently as the v-table, is the mechanism through which a framework can manage an instance of the algorithm. 24. in order for an application to use the FIR algorithm. These levels are outside the scope of the present invention as they do not need to be addressed in order to implement the present invention. Also, as per arrow 810, once step 802 is complete, the framework may choose to execute step 807. These functions are described in previously herein. The algorithm instance is now ready to execute. In step 2611a, client 12606 calls alginit( ) to initialize the instance object.
