Processor for realizing at least two categories of functions
First Claim
Patent Images
1. A processor for realizing at least two categories of functions, comprising:
- a printed memory array for storing at least a first portion of a first look-up table (LUT) for a first mathematical function, wherein data in said first LUT are physically written into said printed memory array during the manufacturing process of said printed memory array;
a writable memory array for storing at least a second portion of a second LUT for a second mathematical function, wherein data in said second LUT can be electrically written into said writable memory array after the manufacturing process of said writable memory array;
wherein said printed memory array and said writable memory array comprise physically different memory cells.

Abstract
The present invention discloses a first preferred processor comprising a fixed look-up table circuit (LTC) and a writable LTC. The fixed LTC realizes at least a common function while the writable LTC realizes at least a non-common function. The present invention further discloses a second preferred processor comprising a two-dimensional (2-D) LTC and a three-dimensional (3-D) LTC. The 2-D LTC realizes at least a fast function while the 3-D LTC realizes at least a non-fast function.
