UPTS集成电路及其开发工具的介绍本电路是一个微处理机,其结构适应于一种特殊的功能类型:对用定点方式编码的数据表进行常规算术计算。它的计算能力很强,这是因为用了两个RAM把数据分开,这两个RAM与含有程序的ROM也是分开的,这样就能在存取一条指令时,同时存取两个数据。强的计算能力还来源于一些专门的计算单元:存贮地址计算单元、线连乘法器、逻辑与算术运算单元。此外,为了方便地将电路与其外围电路连接,还配备了两根各为16位的双向母线。第一根母线通过“信箱”交换来传送数据,电路的寻址空间为64K字。第二根母线通过一个通用的微处理机方便地控制电路(对内部存贮器和寄存器进行存取、停止存取,在程序任何一个输入点上重新运行)。该母线还能执行UPTS的指令输入,既能以内部ROM扩展方式,也能以在外部系统地存贮指令(仿真、小指
INTRODUCTION TO UPTS INTEGRATED CIRCUITRY AND ITS DEVELOPMENT TOOLS This circuit is a microprocessor that is structured to accommodate a specific type of function: conventional arithmetical calculations of fixed-point-encoded data tables. Its computational power is very high, because it uses two RAMs to separate the data, and the two RAMs are separate from the ROMs containing the programs so that they can access two data at the same time when accessing an instruction. Strong computing power also comes from a number of specialized computing units: memory address calculation unit, line multiplier, logic and arithmetic unit. In addition, two 16-bit bi-directional buses are also included for easy connection of the circuit to its peripheral circuitry. The first bus through the “mailbox” exchange to send data, the circuit addressing space is 64K words. The second bus conveniently controls the circuit through a general-purpose microprocessor (accessing internal memory and registers, stopping access, and re-running at any point of the program). The bus can also perform UPTS instruction input, both in the internal ROM expansion mode, but also in the external system to store instructions (simulation, the little finger
