Abstract

An apparatus and method for processing ultrasound data is provided. The apparatus includes an interface operatively connected to a memory, a programmable single instruction multiple data processor (or two symmetric processors), a source of acoustic data (such as a data bus) and a system bus. The memory stores data from the processor, ultrasound data from the source, and data from the system bus. The processor has direct access to the memory. Alternatively, the system bus has direct access to the memory. The interface device translates logically addressed ultrasound data to physically addressed ultrasound data for storage in a memory. The translation is the same for data from both the processor and the source for at least a portion of a range of addresses. The memory stores both ultrasound data and various of: beamformer control data, instruction data for the processor, display text plane information, control plane data, and a table of memory addresses. One peripheral connects to the ultrasound apparatus. An interface adapter, powered from the ultrasound apparatus, translates information transferred between the peripheral and the ultrasound apparatus. The adapter connects non-standard peripherals to various standard interfaces on the ultrasound apparatus.

Claims

1. A method for operating an ultrasound system, the method comprising the steps of:

(a) providing first and second control processors with a common host bus;

(b) storing ultrasound operating system code in a memory; and

(c) executing the ultrasound operating system code on both the first and second control processors.

2. The method of claim 1 wherein the step (c) comprises providing input/output symmetry for the first and second control processors.

3. The method of claim 2 wherein the step (c) comprises using the same input/output ports and interrupt controllers for both the first and second control processors.

4. The method of claims 2 wherein the step (c) comprises providing memory symmetry for the first and second control processors.

5. The method of claims 1 wherein the step (c) comprises providing memory symmetry for the first and second control processors.

6. The method of claim 5 wherein the step (c) comprises using the same memory addresses for both the first and second control processors.

7. The method of claim 6 wherein the step (c) comprises accessing the memory through an interface device operatively connected to the first and second control processors.

8. The method of claim 1 wherein the step (c) comprises providing control instructions.

9. The method of claim 8 further comprising the step (d) of processing ultrasound image data with the first and second control processors.

10. An ultrasound system for controlling the acquisition of image data, the system comprising:

a memory for storing ultrasound operating system code;

first and second control processors both responsive to the same ultrasound operating system code; and

a common host bus operatively connected to the first and second control processors.

11. The system of claim 10 further comprising input/output ports and interrupt controllers operatively connected to both the first and second control processors.

12. The system of claim 11 wherein the first and second control processors use the same memory addresses.

13. The system of claim 12 further comprising an interface device operatively connected to the memory, an ultrasound system control path and the first and second control processors.

14. The system of claim 13 wherein the interface device comprises an ultrasound data bus port and a system bus port, the ultrasound data bus port, the first and second control processors, and the system bus port operable to directly access the memory.

15. The system of claim 10 wherein the first and second control processors are operable to provide control instructions.

16. The system of claim 10 wherein the first and second control processors each comprise a single instruction multiple data processor.

17. The system of claim 10 wherein the first and second control processors provide control instructions and process ultrasound image data.
