摘要： A microcontroller capable of improving processing performance as a whole by executing different programs by a plurality of CPUs and capable of detecting abnormality for safety-required processing by evaluating results of the same processing executed by the plurality of CPUs. A plurality of processing systems including CPUs and memories are provided, data output from the CPUs in each of the processing systems is separately compressed and stored by compressors for each of the CPUs, respectively. The compressed storage data is mutually compared by a comparator, and abnormality of processing can be detected when the comparison result indicates a mismatch. Even when the timings by which the same processing results are obtained are different when the plurality of CPUs asynchronously execute the same processing, the processing results of both of them can be easily compared with each other since compression is carried out by the compressors. Moreover, since the comparison of the comparator is enabled when comparison enable is given from all the CPUs, the comparison operation result can be obtained based on the timing at which the results of compression by the plurality of compressors are determined.
摘要翻译：一种微控制器，其能够通过由多个CPU执行不同的程序来提高处理性能，并且能够通过评估由多个CPU执行的相同处理的结果来检测用于安全需要的处理的异常。提供了包括CPU和存储器在内的多个处理系统，每个处理系统中的CPU输出的数据分别由用于每个CPU的压缩机压缩和存储。压缩存储数据由比较器相互比较，当比较结果表示不匹配时，可以检测出异常处理。即使当多个CPU异步执行相同的处理时，获得相同处理结果的定时也是不同的，因此压缩机进行压缩，因此可以容易地将它们的处理结果进行比较。此外，由于在从所有CPU给出比较使能时能够进行比较器的比较，所以可以基于确定多个压缩机的压缩结果的定时来获得比较运算结果。

摘要： This method is an error correction method such that, when an error is detected in a CPU with pipeline struct, a content of a register file is restored by a delayed register file which holds an execute completion state of an [Instruction N] correctly executed before this error, and a rollback control that re-executes an instruction from the [Instruction N+1] which is the next instruction of the [Instruction N] is performed. The method collects a parity check result of arbitrary Flip-Flops existing inside the CPU, and detects an error. As a result, the content of the register file is restored into the instruction execute completion state preceding to the instruction range likely to malfunction by the error, and the instruction can be roll backed from the beginning of the instruction range likely having malfunctioned by the error.

摘要： A floating-point arithmetic processing apparatus has a circuit for generating a limit value for normalization shift by subtracting an exponent of the minimum value of a normalized number from a value of an exponent of an intermediate result, and a circuit for generating, as a normalization shift number, smaller one of a shift number necessary for making the mantissa of the intermediate result a normalized number and the limit value for normalization shift. The floating-point arithmetic processing apparatus further has a circuit having a circuit for detecting a condition for overflow before the rounding process and a circuit for generating a value in the case of overflow, so that a predetermined value is delivered as a final result only when the overflow condition is detected before the rounding process but in the other case, a result obtained by performing the normalization process and the rounding process is delivered. When no overflow takes place before the rounding process but overflow occurs after the rounding process, the result obtained by performing the normalization process and the rounding process is delivered as a final result.

摘要： A micro-controller includes a dictionary memory for storing instruction codes which appear in a program, and a compressed code memory for storing compressed codes each converted from each of the instruction codes included in the program. Each compressed code has a word length sufficiently long to identify all instruction codes included in the program. Each compressed code has a value indicative of an address in the dictionary memory at which an associated instruction code is stored. The micro-controller is responsive to an instruction code read request which specifies an address of a compressed code to read the compressed code stored in the specified address in the compressed code memory, and to subsequently read an instruction code stored in an address indicated by the compressed code in the dictionary memory.
