It offers a variety of data types, including bits, bytes, 16-bit and 32-bit integers, and 32-bit and 48-bit floating point numbers. It provides 13 addressing modes, including direct, indirect, indexed, based, based indexed and immediate long and short, and it can access 2 MWords of segmented memory space (64 KWords segments). The PACE1750A offers a well-rounded instruction set with 130 instruction types, including a comprehensive integer, floating point, integer-to-floating point and floating point-to-integer set, a variety of stack manipulation instructions, high level language support instructions such as Compare Between Bounds and Loop Control Instructions. It also offers some unique instructions such as vectored l/O, supports executive and user modes, and provides an escape mechanism which allows user-defined instructions using a coprocessor. The chip includes 16 general purpose registers, 8 other user-accessible registers, and an array of real time application support resources, such as 2 programmable timers, a complete interrupt controller supporting 16 levels of prioritized internal and external interrupts, and a faults and exceptions handler controlling internally and externally generated faults. The microprocessor achieves very high throughput of 2.6 MIPS for a standard real time integer/floating point instruction mix at a 40 MHz clock. It executes integer Add in 0.1 µs, integer Multiply in 0.575 µs, Floating Point Add in 0.7 µs, and Floating Point Multiply in 1.075 µs, for register operands at a 40 MHz clock speed. The PACE1750A uses a single multiplexed 16-bit parallel bus. Status signals are provided to determine whether the processor is in the memory or I/O bus cycle, reading and writing, and whether the bus cycle is for data or instructions. The basic bus cycle is 4 clocks long. The PACE1750A will extend the cycle by insertion of wait states in the address and data phases (in response to RDYA and RDYD signals, repectively) and will hold the machine in HI-Z if this CPU has not acquired the bus. A typical non-bus cycle is three clocks long. However, variable length cycles are used for such repetitive operations as multiply, divide, scale and normalize, reducing significantly the number of CPU CLOCKS per operation step and resulting in very fast integer and floating point execution times.
