his packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate.
The simulation is written for static channel and AWGN noise. The packet include:
1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)
2) Modulator (RRC filter)
3) Demodulator (Matched Filter, RAKE receiver)
4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).
You should run "Simulation.m" function that include all modules.
一個簡單的SPI IP核,SPI Core Specifications 可以從說明文檔中找到!
The simple Serial Peripheral Interface core is an enhanced version of the Serial Peripheral Interface found on Motorola s M68HC11 family of CPUs. The Serial Peripheral Interface is a serial, synchronous communication protocol that requires a minimum of 3 wires.
FEATURES:
· Compatible with Motorola’s SPI specifications
· Enhanced M68HC11 Serial Peripheral Interface
· 4 entries deep read FIFO
· 4 entries deep write FIFO
· Interrupt generation after 1, 2, 3, or 4 transferred bytes
· 8 bit WISHBONE RevB.3 Classic interface
· Operates from a wide range of input clock frequencies
· Static synchronous design
· Fully synthesizable
tServer task executes functions at low priority (254). serverSend
funtion is used to send a request to the tServer to execute a
function at the tServer s priority.
First tServer task executes the i() system call to print the summary
of tShell task. Next an address exception is caused in tServer
task by trying to execute a funtion at non-aligned word boundry.
As a result SIGBUS signal is raised automatically. Signals
(setjmp() and longjmp()) are used to allow the tServer task to
recover gracefully from an address error exception. For more
information about signals, please refer to sigLib manual pages.
CCS編程環境 使用的是匯編加C的混合編程方法:
The programme of the Correlation Algorithm.
Using INT2 to get the input signal.
Array x, in first step, is the input signal produced by programme,
in next step, is the input signal get from A/D,
the length is 128, 32-bit floating point.
Array y, in first step, is the input signal produced by programme,
in next step, is the input signal get from A/D,
the length is 128, 32-bit floating point.
Array cor is the Correlation result, the length is 255, 32-bit floating point.
