The list ++ represents the set of modules which are currently loaded in the DSP memory. ++ The first entry in the list is a header record which contains a flag ++ representing the state of the list. The rest of the entries in the list ++ are module records. ++ ++ Global symbol _DLModules designates the first record in the list (i.e. the ++ header record). This symbol must be defined in any program that wishes to ++ use DLLview plug-in. ++ ++ String Representation: ++ ---------------------- ++ The string names of the module and its sections are stored in a block of ++ memory which follows the module record itself. The strings are ordered: ++ module name first, followed by section names in order from the first ++ section to the last. String names are tightly packed arrays of 8-bit ++ characters (two characters per 16-bit word on the C55x). Strings are ++ zero-byte-terminated. ++ ++ Creating and updating the list: ++------------------------------- ++ Upon loading a new module into the DSP memory the dynamic loader inserts a ++new module record as the first module record in the list. The fields of ++ this module record are initialized to reflect the properties of the module. ++ The dynamic loader does NOT increment the flag/counter in the list's header ++ record. ++ ++ Upon unloading a module from the DSP memory the dynamic loader removes the ++module's record from this list. The dynamic loader also increments the ++ flag/counter in the list's header record to indicate that the list has been ++ changed. ++ ++============================================================================*/ ++ ++#ifndef _MODULE_LIST_H_ ++#define _MODULE_LIST_H_ ++ ++#include ++ ++/* Global pointer to the modules_header structure*/ ++#define MODULES_HEADER "_DLModules" ++#define MODULES_HEADER_NO_UNDERSCORE "DLModules" ++ ++/* Initial version number*/ ++#define INIT_VERSION 1 ++ ++/* Verification number -- to be recorded in each module record */ ++#define VERIFICATION 0x79 ++ ++/* forward declarations */ ++struct dll_module; ++struct dll_sect; ++ ++/* the first entry in the list is the modules_header record; ++ * its address is contained in the global _DLModules pointer */ ++struct modules_header { ++ ++ /* Address of the first dll_module record in the list or NULL. ++ Note: for C55x this is a word address (C55x data is word-addressable)*/ ++ u32 first_module; ++ ++ /* Combined storage size (in target addressable units) of the ++ * dll_module record which follows this header record, or zero ++ * if the list is empty.

The GPP is considered the master or "host" processor, and the ++attached DSPs are processing resources that can be utilized by applications ++and drivers running on the GPP. ++ ++The abstraction that DSP/BIOS Bridge supplies, is a direct link between a GPP ++program and a DSP task. This communication link is partitioned into two ++types of sub-links: messaging (short, fixed-length packets) and data ++streaming (multiple, large buffers). Each sub-link operates independently, ++and features in-order delivery of data, meaning that messages are delivered ++in the order they were submitted to the message link, and stream buffers are ++delivered in the order they were submitted to the stream link. ++ ++In addition, a GPP client can specify what inputs and outputs a DSP task ++uses. DSP tasks typically use message objects for passing control and status ++information and stream objects for efficient streaming of real-time data. ++ ++GPP Software Architecture ++========================= ++ ++A GPP application communicates with its associated DSP task running on the ++DSP subsystem using the DSP/BIOS Bridge API. For example, a GPP audio ++application can use the API to pass messages to a DSP task that is managing ++data flowing from analog-to-digital converters (ADCs) to digital-to-analog ++converters (DACs). ++ ++From the perspective of the GPP OS, the DSP is treated as just another ++peripheral device. Most high level GPP OS typically support a device driver ++model, whereby applications can safely access and share a hardware peripheral ++through standard driver interfaces. Therefore, to allow multiple GPP ++applications to share access to the DSP, the GPP side of DSP/BIOS Bridge ++implements a device driver for the DSP. ++ ++Since driver interfaces are not always standard across GPP OS, and to provide ++some level of interoperability of application code using DSP/BIOS Bridge ++between GPP OS, DSP/BIOS Bridge provides a standard library of APIs which ++wrap calls into the device driver. So, rather than calling GPP OS specific ++driver interfaces, applications (and even other device drivers) can use the ++standard API library directly. ++ ++DSP Software Architecture ++========================= ++ ++For DSP/BIOS, DSP/BIOS Bridge adds a device-independent streaming I/O (STRM) ++interface, a messaging interface (NODE), and a Resource Manager (RM) Server. ++The RM Server runs as a task of DSP/BIOS and is subservient to commands ++and queries from the GPP. It executes commands to start and stop DSP signal ++processing nodes in response to GPP programs making requests through the ++(GPP-side) API. ++ ++DSP tasks started by the RM Server are similar to any other DSP task with two ++important differences: they must follow a specific task model consisting of ++three C-callable functions (node create, execute, and delete), with specific ++sets of arguments, and they have a pre-defined task environment established ++by the RM Server. ++ ++Tasks started by the RM Server communicate using the STRM and NODE interfaces ++and act as servers for their corresponding GPP clients, performing signal ++processing functions as requested by messages sent by their GPP client. ++Typically, a DSP task moves data from source devices to sink devices using ++device independent I/O streams, performing application-specific processing ++and transformations on the data while it is moved.
