cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide.
the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972.
here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation.
you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.
full wave rectifierDuring the period from 偽 to 蟺, the input voltage vs input current is are positive and the power flows from supply to the load. The converter is said to be operated at rectification mode .During the period from 蟺 to 蟺+偽 , the input voltage vs is negative and the input current is is positive and reverse power flows from load to the supply. The converter is said to be operated in inversion mode. Depending on the value of 偽, average output voltage can be either positive or negative and hence provides 2 quadrant operation.
The main MIPS processor of SMP8630 comes with a JTAG interface, allowing:
access to caches and data bus (DRAM) with a bandwidth of about 200kbit/s
examining the processor state whatever the execution mode (monice)
connecting to monice using mdi-server and using a gdb client on the processor to step and break
accurately whatever the execution mode
running semi-hosted applications
fl ash write tool
memory testing (MT command)
real-time traces: has not been built in CPU (Config3_TL=0) and only supported by MajicPLUS probes
(maybe built into emulator?)
DragonRaja Client source version 1.4+
this source allow players join in (Hades Warfield or Monsters warfield).
When you compile in debug mode, it is GMtool.
else compile in release mode, it is Normal player.
1. This BSP can support 2443EVT0 board.
If you want to use EVT0 BSP, set followings.
In smdk2443\smdk2443.bat file
set BSP_EVT1=1
-> set BSP_EVT1=
In smdk2443\src\inc\bsp_cfg.h file
#define EVT1
-> #define EVT0
2. Default system tick mode is changed. The value is fixed tick.
Fixed tick means that tick interrupt is occurred every 1ms.
Variable tick means that timer interrupt period is changed when power mode is in idle.
For changing to variable tick
In smdk2443\src\inc\bsp_cfg.h file
#define FIXEDTICK
-> #define VARTICK
In smdk2443\src\Common\Timer\Sources file
SOURCES= timer_fixedtick.c watchdog.c
->
SOURCES= timer_vartick.c watchdog.c

DESCRIPTION:
This example should be used together with ex2a-tx433.asm. One nRF9E5
evaluation board (receiver) should be programmed with the hex-file generated
from assembling this file and the other evaluation board (transmitter)
programmed with the hex-file generated from assembling ex2a-tx433.asm.
All switches on the DIP-swith S206 on the receiver must be set to the "on"
position and all switches on the DIP-swith S205 on the transmitter must be
set to the "on" position.
When one of the switched SW1-SW4 on the transmitter is pressed the
corresponding LED on the receiver is turned on.
The functionality is the same as in ex2c-rx.c.
