ADSP-2186 –2– REV. 0 biased rounding, result free ALU operations, I/O memory trans- fers and global interrupt masking for increased flexibility. Fabricated in a high speed, double metal, low power, CMOS process, the ADSP-2186 operates with a 30 ns instruction cycle time. Every instruction can execute in a single processor cycle. The ADSP-2186?[...]

ADSP-2186 –3– REV. 0 The shifter can be used to efficiently implement numeric format control including multiword and block floating-point representations. The internal result (R) bus connects the computational units so the output of any unit may be the input of any unit on the next cycle. A powerful program sequencer and two dedicated data addr[...]

ADSP-2186 –5– REV. 0 To minimize power consumption during power-down, configure the programmable flag as an output when connected to a three- stated buffer. This ensures that the pin will be held at a constant level and not oscillate should the three-state driver’s level hover around the logic switching point. Interrupts The interrupt control[...]

ADSP-2186 –6– REV. 0 Idle When the ADSP-2186 is in the Idle Mode, the processor waits indefinitely in a low power state until an interrupt occurs. When an unmasked interrupt occurs, it is serviced; execution then continues with the instruction following the IDLE instruction. In Idle mode IDMA, BDMA and autobuffer cycle steals still occur. Slow [...]

ADSP-2186 –7– REV. 0 Clock Signals The ADSP-2186 can be clocked by either a crystal or a TTL- compatible clock signal. The CLKIN input cannot be halted, changed during operation or operated below the specified frequency during normal opera- tion. The only exception is while the processor is in the power- down state. For additional information, [...]

ADSP-2186 –8– REV. 0 There are 8K words of memory accessible internally when the PMOVLAY register is set to 0. When PMOVLAY is set to some- thing other than 0, external accesses occur at addresses 0x2000 through 0x3FFF. The external address is generated as shown in Table II. Table II.

ADSP-2186 –9– REV. 0 Byte Memory The byte memory space is a bidirectional, 8-bit-wide, external memory space used to store programs and data. Byte memory is accessed using the BDMA feature. The byte memory space consists of 256 pages, each of which is 16K × 8. The byte memory space on the ADSP-2186 supports read and write operations as well as[...]

ADSP-2186 –10– REV. 0 Bootstrap Loading (Booting) The ADSP-2186 has two mechanisms to allow automatic load- ing of the internal program memory after reset. The method for booting is controlled by the Mode A, B and C configuration bits as shown in Table VI. These four states can be compressed into two-state bits by allowing an IDMA boot with Mod[...]

ADSP-2186 –11– REV. 0 configured as an input is synchronized to the ADSP-2186’s clock. Bits that are programmed as outputs will read the value being output. The PF pins default to input during reset. In addition to the programmable flags, the ADSP-2186 has five fixed-mode flags, FLAG_IN, FLAG_OUT, FL0, FL1 and FL2. FL0-FL2 are dedicated outpu[...]

ADSP-2186 –12– REV. 0 The EZ-ICE ® * connects to your target system via a ribbon cable and a 14-pin female plug. The female plug is plugged onto the 14-pin connector (a pin strip header) on the target board. Target Board Connector for EZ-ICE ® * Probe The EZ-ICE ® * connector (a standard pin strip header) is shown in Figure 7. You must add t[...]
