Abstract: In a computer system the instruction decoding unit for translating program instructions to microcode instructions operates dynamically. Thus the unit receives state signals indicating the state of the computer, such as a trace enabling signal (63), influencing the translation process in the instruction decoding unit. These state signals (63) are added to the operation code (65) of the program instruction to be decoded, the operation code of the program instruction thus being extended and used as input to a translating table (55), the extended operation code of the program instruction being taken as an address of a field in the table. The addresses and thus the contents of the fields addressed for the same operation code of a program instruction can then be different for different values of the state signals. Thus generally, the state signals cause the instruction decoder to change its translating algorithm so that the decoder can decode an operation code differently depending on the state which the signals adopt. The dynamic decoding can for a trace enabling signal be used for switching on and off a trace function. In the normal case, when tracing is not desired, no microinstructions supporting the trace function have to be executed and thereby the performance and in particular the speed of the computer system will be increased.

Abstract: The present invention relates to a fault testing in digital systems and devices therefor. A processor unit (2) is made available from other activities and the logical units to be tested are set to a predetermined state. An output response analyser (3) is activated and the processor unit (2) generates a set of stimuli, influencing the appropriate logical units. The output response analyser (3) collects responses of the stimuli at different nodes (13) in the digital system (1) and creates signatures from them. The signals are verified and if a fault is noticed, this error is noticed. Preferably, the present state of the processor (2) and other logical units are stored in a storage means (15) prior to the test and recovered after the testing is finished. The invention functions both at chip and board levels, and on systems with several units.

Abstract: When decoding instructions of a program to be executed in a central processing unit (9) comprising pipelining facilities for fast instruction decoding, part of the decoding is executed or the decoding in pipelining units is prepared in a remapping unit (5) during loading a program into a program or primary memory (7) used by the central processor, the remapping or predecoding operation resulting in operation codes which can be very rapidly interpreted by the pipelining units of the central processor. Thus, the operation code field of an instruction is changed to include information on e.g. instruction length, jumps, parameters, etc., this information indicating the instruction length, whether it is a jump instruction or has a parameter etc. respectively, in a direct way that allows the use of simple combinatorial circuits in the pipelining units. This makes it possible to obtain a decoding of complex instructions using few clock cycles, and also that old type instructions can be used as input to the system without degrading the time performance of the instruction decoding. Also, accesses of the program memory (7) and a data memory (11) can be made earlier during execution of a program, which saves execution time.
Abstract translation: 当在包括用于快速指令解码的流水线设施的中央处理单元(9)中执行的程序的指令解码时,在加载程序期间执行部分解码或者在重映射单元(5)中准备流水线单元中的解码 写入由中央处理器使用的程序或主存储器(7)中,重映射或预解码操作产生操作代码,其可由中央处理器的流水线单元非常快速地解释。 因此,指令的操作码字段被改变以包括关于例如 指令长度,跳转,参数等,该信息分别表示指令长度,是跳转指令还是具有参数等,以直接的方式允许在流水线单元中使用简单的组合电路。 这使得可以使用少量时钟周期来获得对复杂指令的解码,并且还可以将旧类型指令用作系统的输入而不降低指令解码的时间性能。 而且,程序存储器(7)和数据存储器(11)的访问可以在执行程序期间提前进行,这节省了执行时间。
