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. For example, an audio -task might perform audio decompression (ADPCM, MPEG, CELP) on data received -from a GPP audio driver and then send the decompressed linear samples to a -digital-to-analog converter. diff --git a/drivers/staging/tidspbridge/Documentation/error-codes b/drivers/staging/tidspbridge/Documentation/error-codes deleted file mode 100644 index ad73cba058eb..000000000000 --- a/drivers/staging/tidspbridge/Documentation/error-codes +++ /dev/null @@ -1,157 +0,0 @@ - DSP/Bridge Error Code Guide - - -Success code is always taken as 0, except for one case where a success status -different than 0 can be possible, this is when enumerating a series of dsp -objects, if the enumeration doesn't have any more objects it is considered as a -successful case.
