This generic layout is also employed in WDM for the class driver and the miniport driver. The ASIC is divided up into two synchronous clocking areas. The entire block of 64 k is addressable via program or data accesses. A subsequent PIO access to PIO address 01 either reads or writes to the indirect address specified by the data previously written to address The host operates on a preprocessed VSP linker output specially formatted for easy processing on the host.

However, since system loading changes dynamically, the next time the same application opens, the VSP may not be overloaded and the process selects a more balanced system option whereby the process allocates or runs the granules on the VSP instead. The enable of the feedback path flip-flop holds the data during other accesses on the same pipe.

Blocks of memory called memory objects are allocated for run-time requirements. The VSP object is created in host memory containing the SrcBuffer struct which contains 544m about the source stream to be processed.

In other embodiments with dynamic linking, the fixed run address feature is relaxed. Note that no interrupt need be sent from the DSP back to the host during processing of the message. When the task finally gets around to updating the audio out buffer, it again places the audio out buffer into the audio out buffer list processed by the mixer. Improvements herein are provided in:. The rest of the data remains on disk as logical or virtual memory.

Each entry in the event table contains a position in bytes and a corresponding event. A value of “0” indicates that the interrupt is masked, corresponding to the way interrupts are masked in the C5x. For example, if data 5m4 written into 0xF, then this value should be 0x The voice codec operates the same way.

Multitasking operating systems such as Windows 95 and NT have multithreading capabilities on which the improvements piggyback. Flashware is implemented as 4 Meg SIMMs plugged into socket-slots in parallel with an additional to main memory The PCI block handles a write that needs to have a different byte alignment.

The pins for both serial ports will be shared. If the subsequent reads are from linear addresses, the address adapyer predicted and the data is cybefstation in time to perform a 0-wait-state read.

The PCI macro control register 0x57 supplies essential information to start, stop, and control the PCI bus interface block. This section is applicable when using the kPCIRequestAdd function, which allows for a PCI request to be created in memory and reused so that the overhead associated with the other PCI functions can be avoided. The Mixer ISR mixes data and fills the empty stereo codec buffer.

System-critical initialization modules to be stored in flash are easily identified because they are logged in the bootlog of the operating system boot sequence. M x is be multiplied by 8 and divided modulo 2 by G x.


Codecs are suitably integrated onto the wrapper chip in some embodiments. Digital signal processors can be adapted for voice recognition, voice synthesis, image processing, image recognition, and telephone communications for teleconferencing and videoteleconferencing.

The subsystem applies the interrupt for two CLKOUT1 periods to insure that the interrupt can be captured during a 1 wait-state write to the interrupt register.

The interrupts are held and driven onto INTA active low.

The VSP, however, uses data aligned as bit words. The DSP processes all of the pages specified by the PageNum parameter, and when finished, checks dwNextPageList to determine the next page list to process. After this initial read, the C5x reads from the address specified by the value SRC. The host message queue works similarly to the DSP message cybeestation only the DSP is placing messages in the queue and the host is receiving them.

In this pass-through mode, the VSP wrapper is either a slave or busmaster. Scalability impacts balance herein. Concurrently executing applications ensure that undesirable overlap does not occur.

This is illustrated in FIG.
