MA^M1^A7¹5⁷⁵0⁰1¹

Radiation Hard MIL-STD-1750A Execution unit

Replaces March 1997 version, DS4548 - 2.3

DS4548 - 3.2 January 2000

The MA17501 Execution Unit is a component of the Dynex

Semiconductor MAS281 chip set. Other chips in the set

include the MA17502 Control Unit and the MA17503 lnterrupt

Unit. Also available is the peripheral MA31751 Memory

Management Unit/Block Protection Unit. These chips in

conjunction implement the full MlL-STD-1750A lnstruction Set.

The MA17501 - consisting of a full function 16-bit ALU, 24 x

16-bit dual-port RAM register file, 32-bit barrel shifter, 4 x 24-

bit parallel multiplier, synchronisation clock generation logic,

and microcode decode logic - provides all computational,

logical, and synchronisation functions for the chip set. Table 1

provides brief signal definitions.

BLOCK DIAGRAM

The MA17501 is offered in several package styles

including; dual-in-line, flatpack and leadless chip carrier. Full

packaging information is given at the end of the document.

FEATURES

■ MIL-STD-1750A Instruction Set Architecture

■ Full Performance over Military Temperature Range

(-55°C to +125°C)

■ Radiation Hard CMOS/SOS Technology

■ 16-Bit Bidirectional Address/Data Bus

■ 16-Bit Full Function Registered ALU

■ 32-Bit Barrel Shifter

■ 24 x 16-Bit Dual-Port RAM File

1.0 SYSTEM CONSIDERATIONS

• 16 User Accessible General Purpose Registers

• 8 Microcode Accessible Registers

The MA17501 Execution Unit (EU) is a component of the

Dynex Semiconductor MAS281 chip set. This chip set

implements the full MlL-STD-1750A instruction set

architecture. The other chips in the set are the MA17502

Control Unit (CU) and the MA17503 Interrupt Unit (IU). Also

available is the peripheral MA31751 Memory Management

Unit/Block Protection Unit (MMU(BPU)).

Figure 1 depicts the relationship between the chip set

components. The EU provides the arithmetic and logical

computation resources for the chip set. The EU also provides

program sequencing logic in support of branching and

subroutine functions. The lU provides interrupt and fault

handling resources, DMA interface control signals, and the

three MIL-STD-1750A timers. The EU and lU are each

controlled by microcode from the CU. The MMU(BPU) may be

configured to provide 1M-word memory management (MMU)

and/or 1K-word memory block write protection (BPU)

functions.

■ 4 x 24-Bit Parallel Multiplier

• 48-Bit Accumulator

• 16-Bit x 16-Bit Multiply in 4 Machine Cycles

■ Instruction Pre-Fetch

■ MAS281 Integrated Built-in Self Test

■ TTL Compatible System Interface
