Attempted execution of any unused opcodes will result in an illegal instruction trap. Digital Signal Processing DSP is used in a wide variety of applications, and it is hard to find a good. For input data greater than 0xFFF, data written to memory is forced to the maximum positive 1.

The SA or SB bit curs set and remains set until cleared by the user. For input data less than 0xFF, data written to memory is forced to the maximum negative 1. If Phase A lags Phase B, then the direction of the motor is deemed negative or reverse. Auth with social network: The output of the sample and hold is the input into the converter which generates the result.

Timers 5×16 bit timers The QEI module provides the ckurs to incremental encoders for obtaining mechanical position data. We think you have liked this presentation. My presentations Profile Feedback Log out.

The index pulse coincides with Phase A and Phase B, both low. Similar operation but single shot. Thus, the PC can address up dspkc 4M instruction words of user program space.


The MSb of the source bit 39 is used to determine the sign of the operand being tested. When bit dspkc overflow and saturation occurs, the saturation logic then loads the maximally positive 1. Feedback Privacy Policy Feedback.

System block diagram A8 version. Ramadan Al-Azhar University Lecture 3.

Published by Candace Morgan Modified over 3 years ago. The OCxR register is compared against the incrementing timer count, TMRy, and the leading rising edge of the pulse is generated at the OCx pin, on a compare match event. If Phase A leads Phase B, then the direction of the motor is deemed positive or forward.

When bit 39 overflow and saturation occurs, the saturation logic loads the maximally positive 9. Ehsan Shams Saeed Sharifi Tehrani. The PWM outputs use push-pull drive circuits. Reads from the latch Dspciread the latch.

One working register W15 operates as a software Stack Pointer for interrupts and calls. The DSP engine also has the capability to perform inherent accumulator-to-accumulator operations which require no additional data.

However, as the dapic is modified Harvard, data can also be present in program space. Bit 31 Overflow and Saturation: An attempt to use an uninitialized W register as an Address Pointer will cause a Reset. When the TxCK pin state is high, the timer register will count up until a period match has occurred, or the TxCK pin state is changed to a low state.


The bit timer has the ability cspic generate an interrupt on period match. A third channel, termed index pulse, occurs once per revolution and is used as a reference to establish an absolute position.

A momentary dip in the power supply to the device has been detected which may dspiic malfunction.

Phase A, Phase B and an index pulse. The OCxRS register is then compared to the same incrementing timer count, TMRy, and the trailing falling edge of the pulse is generated at the OCx pin, on a compare match event.

ACCB overflowed into guard bits 3. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port.

Convergent or unbiased rounding operates in the same manner as conventional rounding, except when ACCxL equals 0x Corus is primarily intended to remove the loop overhead for DSP algorithms. All port pins are defined as inputs after a Reset. Input capture is useful for such modes as:
