## Abstract

A processing device is provided. A cluster includes a plurality of groups of processing elements. A multi-word device is connected to the processing elements within the groups. Each processing element in a particular group is in communication with all other processing elements within the particular group, and only one of the processing elements within other groups in the cluster. Each processing element is limited to operations in which input bits can be processed and an output obtained without reference to other bits. The multi-word device is configured to cooperate with at least two other processing elements to perform processing that requires reference to other bits to obtain a result.

## Claims

### Claim 1

A processing device, comprising:
a cluster including a plurality of groups of processing elements;
a multi-word device connected to the processing elements within the groups;
each processing element in a particular group being in communication with:
all other processing elements within the particular group; and
only one of the processing elements within other groups in the cluster;
wherein each processing element is limited to operations in which input bits can be processed and an output obtained without reference to other bits; and
wherein the multi-word device is configured to cooperate with at least two other processing elements to perform processing that requires reference to other bits to obtain a result.

### Claim 2 (depends on 1)

The processing device of claim 1, wherein the multi-word device provides its output to at least one of the at least two processing elements.

### Claim 3 (depends on 1)

The processing device of claim 1, wherein the processing elements can be configured to provide processing selected from the group including AND and OR.

### Claim 4

The processing device of claim wherein the multi-word device is separated into portions for providing addition, multiplication, and shifting.

### Claim 5 (depends on 1)

The processing device of claim 1, herein the multi-word device can be configured to provide processing selected from the group including addition, subtraction, multiplication, signed multiplication, compare less than, signed compare less than, left. shift, right shift, and arithmetic right shift.
