PA-RISC Processors PA-7200 (PCX-T’) 2.2.7 PA-7200 (PCX-T’) Overview The PA-7200 completely revised the PA-7100 processor core, leveraging only the FPU in its release in early 1995. Being a two-way superscalar processor, the PA-7200 can dispatch and execute two separate instructions at a time to its functional units. In contrast to the PA-7100 it has two separate integer ALUs and thus can execute two ALU integer operations simultaneously. Other changes include a redesigned cache architecture — while retaining the general cache layout with large off-chip L1 caches at CPU clock speed — and use of the Runway processor bus, carried on to later PA-8x00 processors. The PA-7200 was targeted towards high-performance general-purpose applications, but also on specialized applications with large working sets which could take advantage of the high-bandwidth bus interface. Details � PA-RISC version 1.1d 32-bit � Three functional units: 2 integer ALUs, 1 Floating Point � 2-way superscalar � SMP-capable � FPU, MMU, cache controller integrated on die, memory and I/O controller separate and off-chip � Five-stage pipeline � 2 KB on-chip “assist” L1 cache, fully associative, holds 64 32-Byte cache lines � Off-chip L1 caches up to 1 MB I and 2 MB D realized in asynchronous SRAMs with one cycle latency � (The 2 KB on-chip assist cache is not really considered a true cache, thus the off-chip cache is the system’s L1 cache.) � Caches are 64-bit per access, direct mapped, parity protected and cycled at CPU speed � Caches are virtually indexed and physically tagged to minimize latency � 120-entry fully associative TLB � 16-entry BTLB � Hardware TLB miss support � Six predecode bits � Support for uncached memory pages � Bi-endian support � Runway system interface, 64-bit wide, 120 MHz, 960 MB/s peak bandwidth, CPU-to-bus frequency ratios of 1.0, 0.75 and .67 processor speed possible � Glueless interface to the Runway system bus for up to four-way SMP (four CPUs on same Runway processor bus) � Can have up to six bus-transactions in progress at once � CPU interfaces to U2 I/O adapters and MMC/SMC memory controllers on the Runway bus 16
PA-RISC Processors PA-7200 (PCX-T’) � Up to 140 MHz frequency with 4.4 V core and 3.3 V I/O voltage � 14.0×15.0 mm 2 die, 1,300,000 FETs, 0.55µ(micron), 3-layer metal CMOS (CMOS14A process) packaged in a 540-pin ceramic PGA package � Power dissipation of 29W at 140 MHz Used in � C100, C110 � D250, D260, D350, D360 � J200, J210 � K100, K200, K210, K220, K400, K410, K420 � Convex SPP1200/CD, SPP1200/XA, SPP1600/CD, SPP1600/XA � Hitachi 9000V VQ200, VQ210, VR100, VR200, VR400 References 1.
