摘要： A computer system (8) comprising a central processing unit (12) and a memory hierarchy. The memory hierarchy comprises a first cache memory (16) and a second cache memory (26). The first cache memory is operable to store non-pixel-information, wherein the non-pixel information is accessible for processing by the central processing unit. The second cache memory is higher in the memory hierarchy than the first cache memory, and has a number of storage locations operable to store non-pixel information (26b) and pixel data (26a). Lastly, the computer system comprises cache control circuitry (24) for dynamically apportioning the number of storage locations such that a first group of the storage locations are for storing non-pixel information and such that a second group of the storage locations are for storing pixel data.

摘要： A microprocessor-based system (2) is disclosed, based on an x86-architecture microprocessor (5). The system includes a memory address space (30) and a input/output address space (40), where input/output operations are performed in an I/O mapped manner. According to a first embodiment of the invention, burstable access is performed to areas of the main memory (32) which are blocked from cache access, by the microprocessor (5) asserting the cache request signal (CACHE#) in combination with the control signal (M/IO#) indicating that an I/O operation is requested. The memory controller (10) interprets this combination as a burst request to the non-cacheable memory location (32), indicates the grant of burst access by asserting the cache acknowledge control signal (KEN#), and the burst memory access is then effected. According to a second embodiment of the invention, burst access to non-cacheable memory space (32) is acknowledged by the memory controller (60) by way of a burst acknowledge signal (BEN#) that is separate from the cache acknowledgment signal (KEN#).
摘要翻译：基于x86架构的微处理器（5）公开了一种基于微处理器的系统（2）。该系统包括存储器地址空间（30）和输入/输出地址空间（40），其中以I / O映射方式执行输入/输出操作。根据本发明的第一实施例，微处理器（5）结合控制信号来确定高速缓存请求信号（CACHE＃），对主存储器（32）的被高速缓存访问阻止的区域执行突发存取（M / IO＃），表示请求I / O操作。存储器控制器（10）将该组合解释为对非可缓存存储器位置（32）的突发请求，指示通过断言高速缓存确认控制信号（KEN＃）来准许突发存取，然后实现突发存储器访问。根据本发明的第二实施例，通过与高速缓存确认信号（KEN）分离的突发确认信号（BEN＃），由存储器控制器（60）确认对非可缓存存储器空间（32）的突发访问＃）。

摘要： A microprocessor-based data processing system (2) in which asynchronous bus transactions are performed is disclosed. The disclosed embodiments include one or more microprocessors (5) of the x86-architecture type, compatible with the P54C bus protocol, preferably Pentium-compatible microprocessors, as the central processing units (CPUs) of the system. A CPU (5.sub.r) requests an asynchronous bus transaction, in a first disclosed embodiment, by presenting a combination of control signals that is unused in conventional x86-architecture systems; the controller chipset (27) determines whether the transaction may be performed in an asynchronous manner, and later returns an acknowledge or non-acknowledge code to the requesting CPU (5.sub.r). The microprocessors (5) include certain pins, in this first embodiment, corresponding to conventional Pentium-compatible output pins but which now have receiver circuitry for receiving the acknowledge and non-acknowledge codes, along with the transaction identifier. If the transaction is accepted as asynchronous, the identifier is used to later identify the transaction when access is granted. A second disclosed embodiment provides an immediate indication of the acceptability of the requested transaction as of the asynchronous type, so that unacceptable transactions may be immediately processed in synchronous fashion. A third disclosed embodiment uses an additional terminal to indicate the acknowledge or non-acknowledge response.
摘要翻译：公开了一种其中执行异步总线事务的基于微处理器的数据处理系统（2）。所公开的实施例包括x86架构类型的一个或多个微处理器（5），与该系统的中央处理单元（CPU）的P54C总线协议（最好是Pentium兼容微处理器）兼容。在第一公开实施例中，CPU（5r）通过呈现在常规x86架构系统中未使用的控制信号的组合来请求异步总线事务; 控制器芯片组（27）确定是否可以以异步方式执行事务，并且稍后向请求CPU（5r）返回确认或非确认代码。微处理器（5）包括某些引脚，在该第一实施例中，对应于常规的奔腾兼容的输出引脚，但是现在具有用于接收确认和非确认代码的接收器电路以及事务标识符。如果事务被接受为异步，则当访问被授予时，该标识符用于稍后识别事务。第二个公开的实施例提供了所述异步类型所请求的交易的可接受性的即时指示，使得不可接受的交易可以以同步的方式被立即处理。第三个公开的实施例使用附加终端来指示确认或非确认响应。

摘要： A system and a method for determining an attitude of a device undergoing dynamic acceleration is presented. A first attitude measurement is calculated based on a magnetic field measurement received from a magnetometer of the device and a first acceleration measurement received from a first accelerometer of the device. A second attitude measurement is calculated based on the magnetic field measurement received from the magnetometer of the device and a second acceleration measurement received from a second accelerometer of the device. A correction factor is calculated based at least in part on a difference of the first attitude measurement and the second attitude measurement. The correction factor is then applied to the first attitude measurement to produce a corrected attitude measurement for the device.

摘要： A processing apparatus, optionally integrated into a device having a plurality of sensors including a magnetometer, generates navigational state estimates for the device. The processing apparatus has a magnetometer-assisted mode of operation in which measurements from the magnetometer are used to estimate the navigational state and an alternate mode of operation in which the navigational state of the device is estimated without measurements from the magnetometer. For a respective time period, the processing apparatus operates in the alternate mode of operation. During the respective time period, the processing apparatus collects a plurality of magnetometer measurements and determines whether they meet measurement-consistency requirements. If the measurements meet the measurement-consistency requirements, the processing apparatus transitions to the magnetometer-assisted mode of operation. If the measurements do not meet the measurement-consistency requirements, the processing apparatus continues to operate in the alternate mode of operation.
