介紹幾種cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options.

This model simulates a CDMA2000 1xRTT Forward link (between Base Station and Mobile Station). In particular, it simulates the Radio Configuration 3 of a Forward Fundamental channel. The block CDMA2k: Initial settings allows you to set different parameters such as data rate, Power Control SubChannel insertion rate, spreading code index, QOSF index and the channel model.

This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain

Addfilter is a command-line application which adds and removes filter drivers for a given drive or volume. It is intended to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to do this by using the SetupDi APIs. The sample works on both x86 and Alpha platforms. It has only been tested in a 32-bit environment. Since Addfilter is not a driver, it does not deal with Plug and Play or Power Management.

The CD Audio sample allows some non-SCSI2 CD ROMs to support audio operations by intercepting the relevant audio ioctls and translating them into the command block(s) expected by the non-compliant cdroms. It supports Plug and Play and Power Management, and is 64-bit compliant.

The flpydisk sample is a floppy driver that resides in the directory \\Ntddk\Src\Storage\Fdc\Flpydsk. It is similar to a class driver in that it sits a level above the floppy disk controller in the driver stack, and brokers communication between the application level and the low-level driver. The floppy driver takes commands from the application and then calls routines in the controller which will in turn perform the actual interaction with the device. The sample compiles in 64-bit, but has not been tested in this environment. It is compatible with x86 and Alpha platforms.
