basic Real Time Arbitrary Generator with Dynamic Memory

Presentation main topics:• The Idea• Requirements• Preliminary Functional Spec• Initial Design (very shortly)• Time Schedule

Real-Time Arbitrary Generator

The Idea:• The Motivation:

• The bottleneck of Arbitrary generator manufacturers is the static memory component.•What makes it a bottleneck:

• It’s Slow• It’s Expensive• It’s embedded into the board

Real-Time Arbitrary Generator

The Idea:• Our Solution:

• Dynamic Memory• such as: DDR2 or DDR3• fast • cheap• easy to replace

Real-Time Arbitrary Generator

The Idea:• Why did not the industry developed Arbitrary generator with dynamic memory until now:

• Real-Time problems:• refreshing• memory control

• Paradigm:• POC?

Real-Time Arbitrary Generator

Requirements:

• Our main Goal:

POC – basic Arbitrary Generator based on Dynamic Memory

RTAG

Real-Time Arbitrary Generator

Requirements:

• 1: The RTAG Gets the Data (waves samples) from the DSP• 2: The RTAG streams the Data forward, starting on trigger (cyclic)

DSP RTAG D/A1 2

Real-Time Arbitrary Generator

Requirements:• Read and Write, simultaneously• Sends Data synchronically• Streams the Data forwards:

• Beside to a initial delay (one clock from trigger) , streams the Data continuously• Output signals frequency rates:

10Hz-50 MHz• Input & Output width: 16 bit

Real-Time Arbitrary Generator

RTAG

Preliminary Functional SPEC:• 1:

• Gets sample wave writes Commands:

• Wave Number (identifier)• Number of points• Data (the wave)

• Gets trigger commands:• which wave to stream on trigger• the trigger

RTAG1 2

Real-Time Arbitrary Generator

Preliminary Functional SPEC:

• 2: Sends Data (to DAC) :• synchronically• cyclic• output streaming frequency rate by request
