DESCRIPTION
Integer Pipeline The RC5000 is a limited dual-issue machine that The RC5000 serves many performance critical utilizes a traditional 5-stage integer pipeline. This basic embedded applications, such as high-end internetinteger pipeline of the RC5000 is illustrated in Figure 1. working systems, color printers, and graphics terminals. The integer instruction execution speed is tabulated The RC5000 is optimized for high-performance appli(in number of pipeline clocks) as follows: cations, with special emphasis on system bandwidth and floating point operations, through integration of highOperation Latency Repeat performance computational units and a high-performance Load 2 1 memory hierarchy. For this class of application, the result is a relatively low-cost CPU capable of approximately 330 Store 2 1 Dhrystone MIPS.

(This presumes, of course, that the operaInstruction Issue Mechanism The RC5000 recognizes two general classes of tion does not miss in the cache.) instructions for multi-issue: * Floating-point ALU * All others These instruction classes are pre-decoded by the RC5000, as they are brought on-chip. The pre-decoded information is stored in the instruction cache. Assuming that there are no pending resource conflicts, the RC5000 can issue one instruction per class per pipeline clock cycle. Note that this broad separation of classes insures that there are no data dependencies to restrict multi-issue. However, long-latency resources in either the floatingpoint ALU (e.g. DIV or SQRT instructions) or instructions in the integer unit (such as multiply) can restrict the issue of instructions. Note that the R5000 does not perform outof-order or speculative execution; instead, the pipeline slips until the required resource becomes available. There are no alignment restrictions on dual-issue instruction pairs. The RC5000 fetches two instructions from the cache per cycle. Thus, for optimal performance, compilers should attempt to align branch targets to allow dual-issue on the first target cycle, since the instruction cache only performs aligned fetches. Instruction Set Architecture The RC5000 implements the MIPS-IV 64-bit ISA, including CP1 and CP1X functional units (and their instruction set).

RC5000 Computational Units The RC5000 contains the following computational units: Integer ALU. The RC5000 implements a full, single-cycle 64-bit ALU for all integer ALU functions other than multiply and divide. Bypassing is used to support back-to-back ALU operations at the full pipeline rate, without requiring stalls for data dependencies. Integer Multiply/Divide Unit. This unit is separated from the primary ALU, to allow these longer latency operations to run in parallel with other operations. The pipeline stalls only if an attempt to access the HI or LO registers is made before the operation completes. Floating-point ALU. This unit is responsible for all CP1/CP1X ALU operations other than DIV/SQRT. The unit is pipelined to allow a single-cycle repeat rate for single-precision operations Floating-point DIV/SQRT unit. This unit is separated from the other floating-point ALU, so that these long latency operations do not prevent the issue of other floating point operations. In addition, the RC5000 implements separate logical units to implement loads, stores, and branches.
Electrical Specifications
Operating Frequency The input clock operates in a frequency range of 33MHz to 100MHz. The pipeline frequency for the RC5000 is 2 to 8 times the input clock (up to the maximum for the speed grade of CPU).
THERMAL CONSIDERATIONS
The RC5000 utilizes special packaging techniques, to improve the thermal properties of high-speed processors. The RC5000 is packaged using cavity down packaging in a 223-pin PGA package with integral thermal slug, and a 272-pin BGA package. These packages effectively dissipate the power of the CPU, increasing device reliability.

COMMERCIAL TEMPERATURE RANGE
The RC5000 utilizes an all-aluminum package with the die attached to a normal copper lead frame mounted to the aluminum casing. Due to the heat-spreading effect of the aluminum, the package allows for an efficient thermal transfer between the die and the case. The aluminum offers less internal resistance from one end of the package to the other, reducing the temperature gradient across the package and therefore presenting a greater area for convection and conduction to the PCB for a given temperature. Even nominal amounts of airflow will dramatically reduce the junction temperature of the die, resulting in cooler operation. The RC5000 is guaranteed in a case temperature range of 0 to +85 C. The type of package, speed (power) of the device, and airflow conditions affect the equivalent ambient temperature conditions that will meet this specification. The equivalent allowable ambient temperature, TA, can be calculated using the thermal resistance from case to ambient (CA) of the given package. The following equation relates ambient and case temperatures: TA = TC - P * CA where P is the maximum power consumption at hot temperature, calculated by using the maximum ICC specification for the device. Typical values for CA at various airflows are shown in Table 1. CA
