本文提出了一种针对任意检查基数设计余数生成器的方法，旨在增强数字电路中算术和逻辑操作的测试能力。通过这种方法，可以降低错误逃逸的概率，提高错误检测效率。此外，还展示了如何将设计的电路嵌入到微程序可编程状态机中进行测试，而不增加额外的测试硬件开销。该方案适用于算术/代数错误控制编码和容错数字设计。

摘要：

Arithmetic and algebraic codes are used in testing to verify arithmetic and logical operations performed by digital circuits. An important unit of the hardware that implements arithmetic codes is a residue generator. This is a circuit that generates the residue of a number with respect to a check base. The existing design methods for residue generators are oriented to the special values of the check base. We propose an approach to designing the residue generators with an arbitrary check base. We show how to reduce the probability of error escape, when this type of generator is used for detecting arithmetic errors. We then demonstrate how to embed the designed circuit into a microprogrammable finite state machine to test its operation without adding test hardware overhead. The proposed scheme can be used in arithmetic/algebraic error-control coding and fault-tolerant digital designs.
